Hannah Takasuka is a DDS/PhD student in the Oral and Craniofacial Sciences Program. She is a 2022 graduate of Johns Hopkins University with majors in biomedical engineering and Spanish. Prior to UCSF, she conducted academic and industry research in cell biology, tissue engineering, and hardware/software development of medical devices. She also underwent orthognathic (corrective jaw) surgery, experiencing first-hand how a severely dysfunctional and unaesthetic orthodontic bite can negatively affect both physical and mental health. This inspired her to shift her focus and pursue studies in dentistry and oral sciences. She is currently exploring dental electronic health record data and leveraging medical electronic health record data to quantify maternal comorbidities for mothers who deliver early preterm (<32 weeks gestational age), late preterm (32-36 weeks), spontaneous preterm (labor and delivery not induced by a doctor), or medically-indicated preterm (induced by a doctor). Outside of research, Hannah enjoys running, soccer, rock climbing, Christian fellowship, learning languages, and community service/advocacy.

Yaen (Yah-En) is a PhD student in the Biological and Medical Informatics program at UCSF. She works on exploring the contributions of Neanderthal introgressed genomic regions in moderns humans and how they affect structural/functional brain phenotypes, along with psychiatric disease risk. Before joining UCSF, she graduated from Northeastern University with a Bachelor’s in Behavioral Neuroscience and a minor in Data Science, studied tau biology at AbbVie, and conducted neuroimaging research though Northeastern University’s Music, Imaging and Neural Dynamics Laboratory and Massachusetts General Hospital’s Eating Disorder Research and Clinical Program. Today, she continues to advocate for diversity in research, increased mental health awareness, and hopes to be a mentor in the spaces she is a part of. Outside of the lab, you can find Yaen being a guest in the Bay Area hip-hop dance community, exploring San Francisco on her bike, playing too much Candy Crush, and crafting.
