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. 

Henry Zheng

Master of Engineering Student

Henry is a graduate student at Cornell studying Computer Science in the College of Engineering. He joined the Signal Science Lab to develop high throughput signal analysis. Although STEM oriented, his interests are varied and diverse. He loves to participate in many extracurriculars inside of school, such as organizing BigRed//Hacks, Cornell University’s collegiate hackathon, and highly-attended recruiting events for the Association of Computer Science Undergraduates. When he’s not in school, he gets a kick out of teaching people how to do various things, such as how to code and how to swim. If he’s not dozing off, you can probably find him either swimming or lifeguarding at the pool, volunteering throughout NYC, or jamming to music and browsing the web.

William Bekerman

Undergraduate Researcher

Will is a third-year undergraduate at Cornell University majoring in Biostatistics and Information Science with a minor in Mathematics. During his time at Cornell, he developed a deep interest in applying statistical and machine learning models to help solve complex problems. Outside of doing research, he is involved with Cornell Data Science, Cornell’s Alpha Phi Omega chapter, and enjoy reading and traveling.

Afnan Arshad
