Dr. Joann B. Sweasy
University of Arizona Cancer Center

Joann B. Sweasy earned her doctoral degree from Rutgers University, studying the role of the RecA protein in the SOS response to DNA damage, under the direction of Dr. Evelyn M. Witkin.   

She initiated her research on the fidelity of DNA synthesis at the University of Washington in Dr. Lawrence Loeb’s laboratory. After joining Yale University School of Medicine in 1993, she rose through the ranks to become the Ensign Professor of Therapeutic Radiology and Associate Director for Basic Sciences at the Yale Cancer Center. She is currently a tenured professor in Cellular and Molecular Medicine and is Associate Director, Basic Sciences at the University of Arizona Cancer Center.

Dr. Sweasy is an internationally recognized expert in the genetics, cell biology, and biochemistry of DNA repair. For the past 25 years, her laboratory has been consistently funded by the National Cancer Institute to study the molecular basis of mutagenesis and dysfunctional DNA repair as they relate to human diseases including cancer and autoimmunity.

Dr. Sweasy’s research team recently discovered that dynamic conformational changes are important for accurate DNA synthesis. The team has also shown that human germline and somatic genetic variants of base excision repair genes are linked to carcinogenesis because they are unable to properly remove damaged DNA bases, leading to genomic instability, mitotic catastrophe, and other cancer-associated phenotypes. The Sweasy laboratory also discovered that aberrant DNA repair leads to the development of lupus. Her current focus in this area is the identification and characterization of germline DNA repair variants that are enriched in individuals with lupus.

Dr. Sweasy has served on the EMGS Council, as a Member of the Executive Committee, Co-leader of the DNA Repair SIG, and is currently the Chair of the Program Committee for the 2020 EMGS meeting.  Dr. Sweasy has significant skills in and commitment to training the next generation of biomedical scientists. Dr. Sweasy is especially proud of being presented with the 2017 Yale Postdoctoral Mentoring Award. Over 50% of her trainees are women and include several individuals from diverse backgrounds. Several of Dr. Sweasy’s projects are collaborative in nature and as the lead P.I., she has successfully directed the studies, ensuring scientific rigor and the use of unbiased methodology, resulting in the publication of several high-quality papers in peer-reviewed journals.

Treasurer Candidate


Dr. Christi A. Walter
UT Health Science Center at San Antonio

Dr. Chris Walter received a Ph.D. from Florida State University, then completed a postdoctoral fellowship at UT MD Anderson Cancer Center.  She completed a second postdoctoral fellowship in human cytogenetics and molecular genetics at UT Health San Antonio and became a diplomate of the American Board of Medical Genetics.

Dr. Walter started as an Assistant Professor in the Department of Cellular & Structural Biology (now Cell Systems & Anatomy), Associate Director of the Clinical Cytogenetics Laboratory, and Director of the Transgenic Rodent facility.  After receiving tenure and moving through the academic ranks, she became Interim Chair then Chair of the Department of Cell Systems & Anatomy, a position she continues today. She served as chair of the NIA B study section and was a member of the Gerontological Society of American Public Policy Committee.  Related activities include service on the Science Advisory Board Chemical Assessment Committee for the EPA, membership on the local host committee for the World Stem Cell Summit 2014, and other professional activities.

Dr. Walter’s research program is multidisciplinary, combining cell and reproductive biology, DNA repair, mutagenesis and aging.  Her laboratory is focused largely on base excision repair and mutagenesis in biological processes such as germ cell aging and hepatocellular carcinoma.  Her laboratory discovered that AP endonuclease (APE1) is a critical factor in these processes using mouse models.  Her lab provided molecular insights into a mechanism that drives the increase in mutations in male germ cells with reproductive aging, a phenomenon known as the paternal age effect. The paternal age effect is associated with diseases such as autism spectrum disorders and several autosomal dominant diseases. Using a mouse model of spontaneous hepatocellular carcinoma, her lab showed that 06-methylguanine-DNA methyltransferase and base excision repair may be important in the etiology and/or treatment of this cancer.

Councilor Candidates


Dr. Melike Caglayan
