David Breslow is an Assistant Professor in the Department of Molecular, Cellular and Developmental Biology at Yale University. David received an A.B. in Biochemical Sciences from Harvard University in 2004, working in the laboratory of Dr. Stuart Schreiber. David then did his graduate work at the University of California, San Francisco in Dr. Jonathan Weissman’s lab. There he developed new high-throughput functional genomic tools for budding yeast and defined the function of Orm family proteins in sphingolipid homeostasis. As a postdoctoral fellow, David worked with Dr. Maxence Nachury at Stanford University, where he used a semi-permeabilized cell system to study protein entry into primary cilia and developed a CRISPR/Cas9-based screening platform to investigate ciliary signaling. A central focus of David’s work has been applying new systematic approaches to address fundamental questions in cell biology, with a current emphasis on the regulation and functions of the mammalian primary cilium. David joined the Yale MCDB faculty in January 2017.

A graduate of the University of Minnesota, Prof. Gary Brudvig earned his Ph.D. at the California Institute of Technology. He joined the Yale faculty in 1982. In addition to serving as a professor in and chair of the Department of Chemistry, he is also Director of the Energy Sciences Institute on Yale's West Campus, is a professor of molecular biophysics and biochemistry and is affiliated with the Yale Center for Green Chemistry.

Brudvig is the project leader of a team of Yale chemists and other scientists who, under the auspices of the U.S. Department of Energy, are hoping to improve the efficiency of solar-energy utilization. Its aim is to attach manganese complexes to titanium dioxide nanoparticles in order to develop a system that will efficiently produce renewable fuel using solar energy.

From 1983 to 1986, Brudvig was a Searle Scholar at Yale. The Searle Scholarship program supports outstanding work by junior faculty members at select academic institutions. He was the Camille and Henry Dreyfus Teacher Scholar, a distinction given to “talented young faculty in the chemical sciences,” from 1985 to 1990. He was an Alfred P. Sloan Research Fellow 1986-1988.

Brudvig was elected to the American Academy of Arts and Sciences in 1995.

Martina Brueckner obtained her BS and MD degrees from the University of Virginia, followed by a Pediatric Residency at the University of Pittsburgh and a Pediatric Cardiology Fellowship at Yale University School of Medicine. Her clinical and research focus is genetics of congenital heart disease (CHD). The goal of the lab's work is to determine the genetic cause and developmental mechanisms underlying CHD with a focus on the function of cilia in heart development. Our work aims to bridge research in the basic developmental biology mechanisms underlying development of the embryonic left-right axis with clinical pediatric cardiology and cardiac genetics.  The laboratory has been integral in understanding the cellular and molecular mechanism underlying vertebrate LR asymmetry, identifying genes and mechanism by which motile and immotile cilia establish an early asymmetric calcium signal that is essential to normal LR development of the heart. As part of the Pediatric Cardiac Genomics Consortium (PCGC), we are now combining our understanding of the basic biology underlying left-right development with state-of-the-art genomic approaches to a more comprehensive understanding of human CHD. We are focusing on the ability to identify the genetic causes of CHD, and to directly test putative genetic causes of human CHD identified from genomic analysis of patient DNA in animal model systems including mouse and zebrafish, and finally to  link genetic and developmental mechanisms of CHD to improved care of patients with CHD.

Dr. Brueckner's clinical focus is on patients with genetic causes of congenital heart disease. It has become increasingly apparent that a large portion of cardiovascular disease in children and adolescents has as its underlying etiology a genetic defect.  Dr. Brueckner co-founded one of the first pediatric cardiac genetics clinics at Yale-New Haven Children's Hospital. The clinic provides comprehensive diagnostic evaluation and follow-up care for patients with genetic-cardiovascular disease. Dr. Brueckner has been a staff cardiologist since completing her fellowship at Yale in 1990.
