    Clinical Expertise:  Dr. Girardi is Co-Director of the Yale Cutaneous Lymphoma Group, Director of the Photopheresis Unit, and Director of the Phototherapy Unit at the Yale Comprehensive Cancer Center and Yale-New Haven Hospital. Dr. Girardi is also an active member of the national and international organizations (United States Cutaneous Lymphoma Consortium, International Society of Cutaneous Lymphoma) that formulate and publish the criteria guidelines for the diagnosis and treatment CTCL, and is executing the largest clinical database for CTCL.  He has published over 150 scientific manuscripts, clinical reports, and chapters, including on the genetic basis of CTCL and a Medical Progress Report for the New England Journal of Medicine.  Dr. Girardi was recently awarded the 2017 Zeligman Award by Johns Hopkins University for his expertise in understanding the genetic and immunologic mechanisms that cause CTCL, and he has delivered over 100 national and international lectures including at the National Institutes of Health, U.S. Food and Drug Administration, Harvard University, University of Pennsylvania, Memorial Sloan Kettering Cancer Center, Moffitt Cancer Center, Kings College London, and Northwestern University. Dr. Girardi is currently Professor, Vice Chair, Residency Director, and NIH T32 Research Fellowship Co-Director for the Department of Dermatology, Yale School of Medicine.   Disease expertise:  the diagnosis and management of cutaneous lymphoma and related conditions, including: mycosis fungoides (MF) cutaneous T cell lymphoma (CTCL) [variants of which include folliculotropic MF, follicular mucinosis MF, hypopigmented (hypomelanotic) MF, pagetoid reticulosis (Woringer-Kolopp disease), erythrodermic MF, tumor-stage (T3) MF, transformed MF (T-MF), large cell transformation MF (LCT-MF), and Sézary syndrome (SS)]; CD30+ lymphoproliferative disorders (CD30+ LPD) including lymphomatoid papulosis (LyP) and anaplastic large cell lymphoma (ALCL); CD4+ small/medium/pleomorphic T cell lymphoma (CD4+ SMPTCL); cutaneous B cell lymphoma (CBCL) [variants of which include primary cutaneous marginal zone B cell lymphoma (PCMZBCL) and primary cutaneous follicle center B cell lymphoma (PCFLBCL); lymphocytoma cutis (pseudolymphoma); parapsorias (including large plaque and small plaque variants); subcutaneous panniculitic T cell lymphoma (SCPTCL); cutaneous CD8+ cytotoxic T cell lymphoma; cutaneous gamma-delta T cell lymphoma; and cutaneous NK/T cell lymphoma.

    Laboratory Research:  During more than 20 years leading an NCI-funded research program at Yale, Dr. Girardi’s laboratory is credited with major contributions to our understanding of skin biology immunology and skin cancer development, including the elucidation of roles for gamma-delta T cells, NKG2D ligands, and Langerhans cells. Dr. Girardi has served as the Co-Director for the Yale Comprehensive Cancer Center’s Immunology and Immunotherapy Program, and is the holder/filer of 4 biomedical patents on cancer diagnosis and treatment and co-founder of two Yale startup companies. Watch a video with Dr. Michael Girardi >>


    Dr. Girardi’s current research projects include:

    • The role of local immune cells in the development of cutaneous carcinogenesis.  Using state-of-the-art genetically engineered mice, immunobiology techniques, and confocal imaging, the Girardi laboratory is dissecting how various immune cells, resident within and recruited to the skin, contribute the skin cancer development.
    • Novel approaches to the diagnosis and treatment of cutaneous T cell lymphoma (CTCL).  Overseeing one of the largest centers for CTCL, Dr. Girardi and colleagues use genetic sequencing and robotic transfer to enhance diagnosis and to screen and develop new pharmaceutical agents in the treatment of this malignancy.
    • Biodegradable nanotechnology in the prevention and treatment of skin cancer. In collaboration with W.M. Saltzman (Professor, Yale Biomedical Engineering) and Douglas Brash (Professor, Genetics), Dr. Girardi’s lab is developing novel strategies for skin cancer prevention and treatment.

    Dr. Girardi’s prior research projects have included:

    1. Identification of genetic drivers of CTCL.  In 2012, we had provided the most comprehensive description of gene copy number alterations in CTCL [J Invest Dermatol, 2012]. More recently, we collaborated (with R. Lifton, Professor and Chair, Yale Genetics, and Panel Co-Chair of the NIH Precision Medicine Initiative) to more fully elucidate the genetic driver’s of CTCL [Nature Genetics, 2015].

PMID: 21209378


    2. Innovation for the management and treatment of CTCL.  Our lab has helped characterize BCL2 inhibition [Blood, 2015] and BET inhibition [Oncotarget, 2018] activity against patient-derived CTCL cells and the potential for synergism with established anti-CTCL agents. We have also collaborated to help decipher the mechanism of ECP/Photopheresis, the most commonly used immunotherapy for CTCL, and developed the first FISH panel for CTCL

    4. Elucidation of immune contributions to carcinogenesis. We established a paradigm for resident immune influences on mutagenesis within epithelial tissues more generally [Science 2012], while definitively demonstrating that LC exert major influences in both stimulating mutagenesis as well as facilitating tumor promotion [J Invest Dermatol 2015a]. We also revealed a major influence for LC in UVB-induced p53 mutant keratinocyte clonal expansion [J Invest Dermatol, 2015b]. In collaboration with W.M. Saltzman, we have developed a translational sub-program of nanoparticle-based prevention of keratinocyte mutagenesis and the tumor-promoting effects of chemical and UVB exposure. This directly led to the development of a novel sunscreen characterized by superior safety and efficacy [Nature Mat, 2015].

    5. Identification of the relative contributions of ab and gd T cells in the regulation of cutaneous malignancy. We were the first to demonstrate the critical contribution of gd T cells to the regulation of cutaneous malignancy [Science, 2001; J Exp Med, 2003a], and our in-depth studies elucidated the differential contributions of gd T cells relative to ab T cells [J Exp Med, 2003b; J Invest Dermatol, 2004]. These findings were made at a time when there was considerable skepticism about the capacity of lymphocytes to control malignancy, and therefore we helped define tumor immunology as a biological and clinical force. We went on to define major roles for these local immune cells in the regulation of the cutaneous stress response so fundamental to carcinogenesis [Nat Immunol 2006; Nat Genet 2008]. We also identified and characterized a novel population of CD8+ tumor-promoting T cells (T-pro) [PNAS 2007] that drives cancer progression, proving that pro-tumor immune components are not confined to regulatory function but also the proactive local production of factors that promote tumor growth [J Invest Dermatol 2010].

    After graduating from Hamilton College as a Chemistry major, Richard Edelson received his MD from the Yale School of Medicine (YSM).  He then sequentially trained in Internal Medicine at the University of Chicago, Dermatology in the Harvard Program and Cancer Immunology at the National Institutes of Health.  Before being recruited back to his alma mater as Chairman and Professor of the YSM Department of Dermatology in 1986, he was Director of the Immunobiology Group in Columbia University’s Comprehensive Cancer Center, Associate Director of that institution’s General Clinical Research Center and Professor and Director of Research in Columbia’s Dermatology Department.

    While on the Yale faculty, he has served continuously as Chairman of the Department of Dermatology (1986-Present), and at overlapping times, has also been the Director of the Yale University Comprehensive Cancer Center (2003-9), YSM Deputy Dean overseeing all Clinical Departments (2000-3), Leader of the YSM Cancer Center’s Lymphoma Research Program and the YSM Faculty Representative to the Yale-New Haven Hospital Board of Trustees. He is an elected member of the American Society for Clinical Investigation and the Association of American Physicians, the Interurban Club, the Lotos Club and an honorary member of several international medical associations.

    He is best known for two discoveries and their development.  First, he introduced the unifying concept of Cutaneous T Cell Lymphoma (CTCL), as a malignancy of skin-homing malignant CD4 T cells.  Second, he devised Extracorporeal Photochemotherapy, which became the first FDA-approved immunotherapy for any cancer.  That therapy, through its induction, antigen loading and modulation of physiologic dendritic antigen presenting cells, is now regularly administered in the majority of university medical centers throughout the USA and Europe, to treat advanced CTCL, rejection of transplanted hearts and lungs, graft-versus-host disease following stem cell transplantation and autoimmune disorders.  More than 70,000 patients have received a total of more than 3 million treatments. 

    He takes great pride in the level and breadth of the international acclaim of the present Yale Dermatology faculty members, all of whom were recruited to the Department on the Edelson watch.  Each of the Department's four clinical sections (Medical, Pediatric and Surgical Dermatology, and Diagnostic Dermatopathology) is led by a recent president of the relevant national society.  The clinical (residency and fellowship) training programs are distinguished by their production of academic and investigative dermatologists, having launched the careers of more than sixty full-time university-based faculty members, including eight current Dermatology Department chairmen (Stanford, Harvard, NYU, Albert Einstein, Howard, Oregon, Vermont and Eastern Virginia), the current Deputy Director of the National Cancer Institute and four current Directors of Dermatologic Surgery (Yale, Stanford, NYU and Vermont).  The Yale Dermatology faculty currently ranks first nationally in its field, in terms of total federally funded dollars of competitive research support.

    Dr. Edelson is the recipient of several National honors, including Castle and Connolly’s National Physician of the Year, the Dermatology Foundation’s Discovery Award, the American Skin Association’s National Mentorship Award and the Society of Investigative Dermatology’s Rothman Award for Career Contributions.  He is one of eight selected graduates of the NIH Physician Scientist Training Program whose investigative careers were featured in an eight-hour audiobook, narrated by actor Alan Alda, released by Audible.Com in December 2020, as a tribute to pivotal federally funded scientifically-driven medical advances.

    Jonathan Leventhal, MD, is the director of the Onco-Dermatology Program at Smilow Cancer Hospital at Yale New Haven. He treats patients undergoing cancer treatment who experience itchy or painful rashes, as well as hair and nail changes that can result from either their disease or treatment, including chemotherapy, immunotherapy, radiation or stem cell transplantation. 

    “One of the most rewarding aspects of my job is improving the quality of life for patients with cancer who are affected by adverse skin events,” he says.Watch a video with Dr. Jonathan Leventhal >>

    Seeing an onco-dermatologist like Dr. Leventhal can make the difference between a patient being able to continue receiving a cancer treatment or having to be taken off it when the skin conditions become too severe. “If left untreated, some skin, hair and nail conditions can become quite debilitating, even disfiguring and may negatively impact health and ability to perform day-to-day activities,” says Dr. Leventhal. He helps to manage these skin problems so that patients with cancer can continue their treatments and enjoy a better quality of life.

    In addition to his role at Smilow, Dr. Leventhal, an assistant professor of dermatology and associate director of the residency program at Yale School of Medicine, cares for patients with a wide range of skin conditions in Yale Medicine Dermatology’s New Haven and Branford locations. He performs routine skin cancer screening examinations and also treats general skin problems—from acne to psoriasis to eczema. He is also the Associate Residency Program Director and is Principal Investigator of several clinical trials involving the management of cutaneous reactions to cancer therapy. 

    "Every day I am excited to come to work, treating various skin conditions affecting my patients and helping patients with cancer continue their potentially life-saving treatments,” says Dr. Leventhal. “Skin diseases can impact the way people see themselves and can affect how people feel, both physically and emotionally. My work is particularly gratifying when I can improve my patients' overall comfort, happiness and health.”

    Alicia Little, MD, PhD, is a dermatologist with expertise in women’s skin health and autoimmunity. 

    She specializes in skin disease of pregnancy and vulvar skin diseases; autoimmune skin diseases including cutaneous lupus, dermatomyositis, morphea, lichen sclerosus, and lichen planus; and inflammatory skin diseases including psoriasis, atopic dermatitis (eczema), and rosacea. She also handles general dermatology, acne, and skin cancer screening.

    “I enjoy meeting new patients and developing lasting relationships with them,” Dr. Little says. “I love looking at my schedule and recognizing patients who I have helped with uncomfortable rashes, acne, or skin cancers, and continuing to support them over the years with any new or chronic skin conditions.”

    Dermatology, she says, allows her to see patients of all ages and to use her background in immunology since many skin diseases and rashes are caused by an overactive immune system. 

    “As dermatologists, we have the wonderful privilege of seeing our patients get better quite literally, since their symptoms are often also visible to us on the skin,” she says.

    When not caring for her patients, Dr. Little, who is an assistant professor of dermatology at Yale School of Medicine, conducts research on the immune cells responsible for autoimmune skin disease. “By studying what is going wrong to cause the body to attack itself, I hope that we can identify targets for future treatments to improve patients’ lives,” she says.

    Peggy Myung is interested in hair follicle development and regeneration. Currently, she studies hair follicle development in mice and has a focus on how the dermal niche regulates hair follicle cell fate decisions. In particular, her work is centered on understanding the epithelial-mesenchymal interactions that regulate epithelial growth and differentiation in an effort to re-purpose these same molecular mechanisms to suppress aberrant growth in carcinogenesis.

    I am a physician-scientist in dermatology, which involves both taking care of patients and advancing scientific research. I see patients at the Yale Medicine dermatology office at 322 East Main St in Branford, CT. I take care of a wide range of dermatologic conditions including autoimmune diseases such as lupus and scleroderma (systemic sclerosis), skin cancer, acne, psoriasis, atopic dermatitis/eczema, and blistering skin diseases. In the laboratory my research primarily focuses on the role of the immune system in scleroderma and chronic graft-vs-host disease, two immune-mediated processes that cause tightening of the skin. To setup an appointment, please contact our office at (203) 481-3419. I look forward to seeing you.

    To Kathleen C. Suozzi, MD, the prevention and reversal of sun damage has become a passion. “In my dermatology care and research, I see how sun exposure leads to the development of skin cancers and causes the skin to age prematurely,” she says.

    Dr. Suozzi specializes in the treatment of skin cancer with a technique called Mohs surgery. The technique is used to remove cancer cells layer by layer, while preserving normal tissue. She received advanced training in dermatologic surgery at Yale School of Medicine. She is widely published in scientific journals and has presented her research about how skin cancer develops at national conferences including the American Academy of Dermatology, the American Society of Dermatologic Surgery, the Society of Investigative Dermatology and the American College of Mohs Surgery.

    She’s committed to alerting people about the dangers of sun exposure. “People accumulate sun damage over a lifetime, starting in childhood. I frequently hear from patients that they were not aware of the risks of sun exposure during their youth,” she says. "But it is never too late to start protecting your skin from UV damage."

    In addition to treating skin cancers, Dr. Suozzi uses advanced technologies such as photodynamic therapy, laser treatments and medications to help treat UV-induced damage to the skin. "These technologies can help reverse visible signs of aging and address precancerous changes in the skin,” she says.

    Mary Tomayko M.D., Ph.D., is a physician scientist who specializes in the diagnosis and treatment of autoimmune blistering disease and other immune-mediated skin disease. Dr. Tomayko directs the Yale Immunobullous Clinic. Upon consultation requests from colleagues, Dr. Tomayko evaluates individuals with complex cutaneous autoimmune and inflammatory disorders such as pemphigus, pemphigoid, epidermolysis bullosa acquisita, atopic dermatitis, vitiligo, alopecia areata and psoriasis. She employs a range of treatment modalities, including the systemic immunomodulators rituximab, intravenous immunoglobulin, omalizumab, dupilumab and ustekinumab, targeted “biologic” agents mycophenolate mofetil, azathioprine and methotrexate and phototherapy. She also performs surgical excisions of skin cancers and skin lesions. Dr. Tomayko is an attending physician at Yale Medicine Dermatology, Yale Health and Yale New Haven Hospital.

    Dr. Tomayko’s research laboratory has 2 intertwined missions. The first is to undercover the underlying mechanism of immune dysregulation in bullous pemphigoid, in order to develop effective targeted and safe treatments for this autoimmune blistering disease. The second is to understand how long-lasting immunity to infection and immunization is established and maintained. In seminal work, she has uncovered unexpected diversity in phenotype and function of the cells that maintain B lymphocyte immunity and has identified novel molecular pathways essential for lasting immunity. This work, funded by the National Institute of Health, suggests exciting new approaches to enhance and suppress immunity therapeutically. Dr. Tomayko publishes peer-reviewed articles and chapters and regularly presents her work at national and international meetings. She is a reviewer for scientific and medical journals and foundations. She is a Medical Editor for Dermatology Focus, a publication that highlights recent advances in the field.

    Dr. Tomayko is a director of dermatology education at Yale University School of Medicine. She mentors undergraduate, graduate and medical students in her laboratory, and trains resident physicians and fellows.

    I am a physician-scientist who has trained in immunology, molecular biology, genetics and clinical dermatology. My overall career goal as a physician-scientist are to integrate fundamental immunology with clinical dermatology. In particular, I am interested in the role of costimulatory and inhibitory immune receptors in cancer immunity, autoimmunity pathogenesis and immunotherapy. My interest in this field was driven by my experience in the Medical Scientist Training Program at Washington University in St. Louis, where I worked in the laboratory of Dr. Robert Schreiber to decipher key molecular regulators of cancer immunoediting. As a consequence, the expertise gained in skin immunology and the emerging immunotherapies to treat melanoma inspired me to become a dermatologist. During my dermatology residency, I joined the laboratory of Dr. Lieping Chen at Yale School of Medicine, who pioneered targeting the PD-1 axis for cancer immunotherapy and has discovered multiple novel immune checkpoint molecules including programmed death receptor-1 homolog (PD-1H) (also known as VISTA). My current research interests include: 1) identification of novel immune checkpoints such as PD-1H/VISTA and others in cutaneous malignancies (e.g., melanoma and keratinocyte carcinomas) and 2) elucidating the inhibitory immune landscape of chronic inflammatory disorders such as psoriasis and cutaneous lupus erythematosus.
