Course Director: Introduction to Genetic Counseling; Foundations of Human Development; Therapeutic Genetic Counseling 1 and 2
I am an ABGC board-certified genetic counselor with over 20 years of experience in clinical care, education, industry work, and research. I believe strongly in the therapeutic potential of genetic counseling and the capacity of our profession to support people engaging with questions about how genetic and genomic medicine impact them as individuals, families, communities, and society. I am originally from Virginia and completed my education in genetic counseling at the University of California, Berkeley where my capstone work addressed the relational impact of infertility on couples. I have worked in clinical practice at the University of California San Francisco Medical Center and Johns Hopkins Hospital, providing inpatient and outpatient genetic counseling services for clients affected by or at risk for a broad range of genetic disorders. I have also worked for several years in advocacy at the National Fragile X Foundation and industry at Ambry Genetics. My research has focused on the process of consent for exome sequencing, health-related quality of life, and the use of patient-reported outcome measures in clinical trials. I have been a faculty member of several genetic counseling graduate programs and have held a variety of leadership positions within NSGC, ABGC, and ACGC. I am currently the Secretary/Treasurer for the Association of Genetic Counseling Program Directors (AGCPD) and a member of the Education Committee of the New York State Genetics Task Force. I joined Columbia University in 2017 as the inaugural program director for the Genetic Counseling Graduate Program.

Assistant Program Director
Course Director: Cancer Genetics; Advanced Counseling Skills; Process Group
Fieldwork Supervisor: Cancer Genetics
I am an ABGC board-certified genetic counselor with over eight years of experience in clinical care, research, and translational genomics. My experience has allowed me to develop a nuanced understanding of both the challenges and successes of genomic medicine and to better appreciate the interface between clinical care and research in genetics and genomics. I am originally from New York and completed my genetic counseling graduate education at the University of Michigan where my research focused on the lived experience of rare disease, particularly around the process and emotional effect of disclosing a diagnosis to peers during adolescence and young adulthood. I have worked in clinical practice at Yale University and Yale-New Haven Hospital, serving as a clinical supervisor and rotation coordinator for genetic counseling students and contributing to programmatic development of the clinical cancer genetics service. I have also worked for several years at the Institute for Genomic Medicine (IGM) at Columbia University Medical Center, where I have focused on the utilization of research whole exome sequencing toward the goal of therapeutic precision medicine in epilepsy. I joined the Columbia University Genetic Counseling Graduate Program in 2018 as the inaugural assistant program director.

I completed my genetic counseling graduate education at Sarah Lawrence College where my thesis focused on the religious ethics of BRCA1 and BRCA2 testing in the Orthodox Jewish population. I also completed a masters in public health at King’s College London where my research explored public interest in direct-to-consumer genetic testing. I have worked in many settings, including prenatal, pediatric, and cancer genetics, as well as in clinical research in Alzheimer disease. I have also served as a course director for Practice of Medicine at King’s College London, offering a comparative look at medicine and healthcare in the US and the UK. These opportunities have given me an appreciation of genetics across the lifespan and around the world.

Ronald Wapner, MD
Professor, Department of Obstetrics & Gynecology
Course Director: Introduction to Precision Medicine
I am an ABMGG and ABOG board-certified OB/GYN with 29 years of clinical experience. I have participated in or led randomized trials evaluating genetic prenatal diagnostic and screening technologies for more than 26 years. These include much of the original work evaluating chorionic villus sampling, biochemical and ultrasound screening for fetal chromosome abnormalities, a prospective comparison of chromosomal microarray to karyotyping for prenatal testing, microarray analysis of stillborn infants, and a comparison of cell-free DNA to biochemical and ultrasound screening in low-risk pregnant woman. My most recent work evaluated the role of expanded pan-ethnic carrier screening in prenatal care, which presented the largest experience of such testing to date and demonstrated racial and ethnic consequences in the screening recommendations, presently in practice. I am currently involved in evaluating the use of whole-exome sequencing in structurally abnormal fetuses. I have extensive experience as a mentor and teacher, serving as the director of fellowship programs at both Jefferson Medical College and Columbia University. I have supervised both clinical and basic science research trainees, many of whom now hold prominent positions at academic institutions and have made significant contributions to research in our field. I joined the Columbia University Genetic Counseling Graduate Program in 2017 as an inaugural co-medical director.
