Karen Tsay

Visiting Graduate Student

Karen is a PhD student in Professor Song-I Han’s lab at UCSB. She obtained her BS in Pharmacological Chemistry with a minor in General Biology from UCSD in 2018. Her research focuses on using DEER spectroscopy to probe the structure transformations of IDPs and conformations of polymers.  Some of her current works include using bootstrapping to derive uncertainty from DEER data and improving background correction of DEER of non-3D samples. Outside of research, Karen likes to explore restaurants and museums.

Yingying Jin

Visiting Graduate Student

Yingying obtained her B.S. degree in Chemical Engineering at UCSB. She is currently a Ph.D. student in a joint program of Professor Steve K. Buratto’s lab and Professor Michael T. Bowers’ lab. She also actively collaborates with Professor Madhur Srivastava’s and Songi Han’s lab. Her research focuses on developing Atomic Force Microscopy (AFM) image analysis methods and using complementary techniques such as Ion Mobility Mass Spectrometry (IM-MS) and DEER spectroscopy to investigate the oligomeric assembly mechanism and early fibril formation of amyloidogenic proteins. Her AFM work has been applied to screen ML-modeled small inhibitor molecules on Abeta42 and TDP43-LCD307-319 designed by a local start-up company named Acelot and founded by UCSB Computer Science Professor Ambuj K. Singh. Outside research, she enjoys exploring new media art exhibitions, morning walks at the local beach, and snowboarding. 

Carissa Nair

Undergraduate Student

Carissa is a biological sciences major and Tanner Dean’s Scholar in the College of Arts and Sciences. She joined the lab in 2022 and will be working on the project to diagnose Amyotrophic Lateral Sclerosis from blood samples by analyzing Cu2+ distances in the SOD1 protein. Previously, she won the Texas Health and Human Services Department’s Innovators in Aging award for her research work in senior living centers. At Cornell, she is involved with the Undergraduate Research Board, Globemed, and Kidney Disease Screening and Awareness program. Outside of science, she’s a choral musician (Soprano 2) and enjoys writing poetry.

Kelly Huang

Undergraduate Researcher

Kelly is a sophomore in the College of Arts and Sciences, majoring in Chemistry. She aspires to work in the pharmaceutical industry, specifically drug discovery and development. She is from New York City and she joined the lab in 2022. She will be conducting research on identifying components of controlled substances, such as cannabis, via EPR spectroscopy. Outside of academics, she enjoys playing chinese yoyo (diabolo), watching true crime videos and discovering new food spots in NYC.
