Graduate Students

Hammad Khan


Hammad joined the lab in the Fall of 2020 to pursue his PhD in Biomedical Engineering.  He graduated in electrical engineering student from Montana State University in 2020. His previous research focused on engineering device applications to better understand neuronal communication. When not in lab, he likes to dive into a good book or two and enjoys hiking. Hammad was a receipient of the Purdue Stephen Ash Fellowship and is also a NIH T32 Trainee. In 2021 Hammad was selected as a mentor for the Honors College.  At Purdue Hammad aims to unravel the role of dendritic hotspots in the hippocampus during place field formation using a combination of electrophysiology, imaging and computation.

Om Kolhe


Om is joining the lab in the Fall of 2020. Om completed his dual B.Tech and M.Tech in electrical engineering from IIT Bombay with a research interest spanning analog CMOS circuit design for sensor systems and wireless transceivers . His research at Purdue would focus on circuits and systems for neural recording and modulation. His past research was focused on designing satellite receivers and oscillators for wireless receivers.

Laura Roa  


Laura joined the lab in Fall of 2019 to pursue her PhD in biomedical engineering.  She completed her undergraduate degree at Arizona State University in Biomedical Engineering.  Laura’s research focuses on unraveling the biophysical and biochemical properties of dendritic spines using a combination of nano-electrophysiology, two-photon calcium imaging, transmitter uncaging, and modeling. Laura is a Purdue Doctoral Fellowship recipient. In 2020 Laura was selected as part of an NIH Training grant to research the role of spines in acoustic feature extraction.

Shulan Xiao


Shulan joined the lab in the summer of 2019 to pursue her PhD in biomedical engineering. She completed her Bachelors of Engineering in Electrical Engineering from Huazhong University of Science and Technology, Wuhan, China. She majored in optoelectronics during this phase. Her research interests include integrated optical devices, microscopy and neuroscience. Shulan’s research focus is on spatial-light-modulator based uncaging and optogenetics and dendritic dynamics during sensory processing and behavior. She uses a combination of in vivo and in vitro whole-cell electrophysiology, single-unit recordings, two-photon calcium imaging, transmitter uncaging, and optogenetics in her research. Shulan was a recepient of the Purdue Stephen Ash Fellowship.
