About Mai Abdusamad:
Mai grew up in Portland, OR. She graduated from UCLA with a major in biochemistry and a minor in biomedical research. At UCLA, she developed an interest in cancer biology while working in the lab of Dr. Jorge Torres where she characterized the role of a novel protein in cell division and its implications in cancer. After graduation, Mai joined the Broad Institute as a research associate and Broad Cancer Genomics Scholar in the lab of Dr. Todd Golub. At the Broad, Mai worked on multiple projects that contribute to the generation of a Cancer Dependency Map—a comprehensive preclinical reference map linking genetic features of cancers to vulnerabilities to identify targets for therapeutic discovery. Outside of the lab, Mai enjoys hiking and watching foreign dramas.

About Dhiraj:
Dhiraj is a first year in the MD/PhD program and loves immunology. His primary interest is in investigating autoimmune diseases but is open to anything related to immunology, including host-pathogen immunology.  Dhiraj investigated sex bias in lupus and semi-invariant T cell biology in the Autoimmunity and Tolerance Laboratory run by Dr. Ram Raj Singh at UCLA. He hopes to continue investigating autoimmune diseases at the basic and translational levels during his training. Dhiraj is also passionate about studying how the social determinants of health can be integrated into precision medicine and hopes to get involved in this work through the UC Davis Center for Precision Medicine and Data Sciences. Dhiraj is also interested in teaching and hopes to find teaching opportunities throughout his training.

Dhiraj is an avid sports fan and loves his hometown Bay Area sports teams, having grown up in San Jose. Dhiraj also loves to run, hike, camp, and try out new restaurants (when there isn’t a pandemic). He also loves reading sci-fi short stories, long form journalism, struggles through the New York Times Crossword, and will never part ways with his HBO subscription.

Anna Sadovnikova, GS5, IBCLC, MPH, MA, is a mammary gland biology and breastfeeding medicine trainee in the Hovey Lab.

Low milk production is one of the main reasons mothers stop breastfeeding. She joined the Hovey Lab because she wanted to build upon the research skills she gained in public health and social entrepreneurship to become a leading physician-scientist in the lactation field. Through her doctoral work, Anna will develop research expertise in comparative mammary gland biology, specifically in the genetic regulation of milk production.

During her dual-masters, Anna focused on international human donor milk banking policies and practices. Anna is the CEO of LiquidGoldConcept, a company specializing in simulation-based training of healthcare professionals in clinical lactation and maternal-child care.

About Annica Stull-Lane:
Annica is fascinated by our microbial world, from the commensal microbiome to pathogens of infectious disease. Microbiological laboratory research became her passion over time through work and research during her liberal arts education at Oberlin College, via a postbaccalaureate APHL/CDC Emerging Infectious Diseases Laboratory Fellowship, and at a startup biotech position. Annica is excited to train at UC Davis, furthering this work that will guide her towards her career goal: to serve as a physician-scientist who heads an academic lab; teaches and mentors; and collaborates with scientists, physicians and patients. She is interested in studying infectious diseases of global and public health importance, elucidating molecular mechanisms of disease, and addressing complex health problems through the One Health approach. In the clinic, Annica values working with underserved populations, improving health outcomes through teamwork and dedication. Ultimately, she looks forward to collaborating with creative thinkers to alleviate health disparities through discovery. Apart from her clinical and research interests, Annica enjoys hiking, cooking, and singing.
