Socially-driven researchers with passion for signal processing

Gyana Sahoo

Postdoctoral Associate

Gyana completed his PhD from Department of Physics, IIT Kanpur, India. His expertise lies in the field of spectroscopy, biomedical imaging and machine learning. In Signal Science Lab, he is working on developing wavelet analysis and image processing methods for improving sensitivity of biophysical methods. He is an active member of PhtoSpIMeDx healthcare start up group. Outside research, he is passionate about cricket and enjoys playing both cricket and badminton.

Aritro Sinharoy

Incoming Postdoctoral Associate

Aritro got his Masters degree in Chemistry from Indian Institute of Technology Bombay, India and successfully defended his doctoral research working at the National Biomedical Center for Advanced ESR Technology (ACERT) at Cornell University in 2015. He has developed an analytic platform using Python for ESR pulsed dipolar signal (PDS) analysis and derived the functional forms of various PDS signals for fast simulations of 1D and 2D spectra. After graduating from Cornell, he has served as an Associate Consultant at IQVIA in NYC, followed by the CEO of in Bangalore, India. His passion is learning new programming languages, creating music, and riding motorcycles.

Nimesh Srivastava

Graduate Student

Nimesh graduated from Manipal University, India with major in Electronics and Communication Engineering. Nimesh joined the Signal Science Lab in 2019 and is working on developing wavelet denoising methods for reducing MRI scans. Outside research, he is involved with Cornell’s International Student Union chapter and enjoy swimming, traveling and a big-time foodie.

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.

Pranav Gupta

Visiting Graduate Student

Pranav is a PhD student at the National Biomedical Center for Advanced ESR Technology (ACERT). He obtained his Bachelors degree in Physics from Indian Institute of Science, Bangalore, India in 2015. His research focuses on developing computational methods to analyze ESR spectra. Some of his recent work included 2D-ELDOR predictions of dynamic exchange between conformations of a spin labelled protein. He loves working with people in other departments in collaborative projects, especially folks from computer science. In his free time, Pranav likes to ride his bike around, read novels, and write silly 2 line poems. 

Leah Woldemariam

Undergraduate Researcher

Leah is a junior Mathematics major concentrating in Applied Mathematics. She joined the lab in 2018 and is currently investigating the properties of Haar transforms. Outside of research, she is also a member of the Milstein Program.

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

Undergraduate Researcher

Afnan Arshad is a Senior in the College of Arts and Sciences, majoring in Computer Science and Economics. He hails from Islamabad, Pakistan, and spent last semester studying abroad in Auckland, New Zealand. He currently works in the Signal Science Lab on optimizing microscopic images using Python. His interests include soccer and poetry. He can be contacted at

Mansi Agarwal

Undergraduate Researcher

Mansi is an undergraduate student at Cornell University, majoring in Computer Science. She took several computer science courses at Stanford Summer Program. Currently, in her internship, she is analysing audit logs from micro-services of an application. She is also working on a research project to develop an algorithm that reduce the bandwidth requirement for live video streaming without comprising the video quality. She is a student mentor for the prestigious Google CSSI-Coursera program. She aspires to build a digital platform that reaches outer areas, small rural entrepreneurs, where buyers and sellers can connect efficiently and securely, and where small entrepreneurs may seek crowd-funds and advice. Thus, giving wings to a million dreams.

Henry Zheng

Undergraduate Researcher

Henry is a junior at Cornell studying Computer Science in the College of Engineering. He joined the Signal Science Lab to develop high throughput video streaming. 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.
