Graduate Students

Yezihalem Mesfin

ymesfin Graduated in 2008 with a BS in Electrical Engineering from University of Minnesota. Currently working full time at Starkey Hearing Technologies in Eden Prairie, Minnesota as a Sr. New Platform Firmware Engineer. My research in this lab focuses on applying mSync neuromodulation techniques for treating tinnitus on human subjects. Future research will explore incorporation of magnetic or ultrasound stimulation and integrative healing techniques into the mSync paradigm.


Hongsun Guo

hguo Graduated with a BS and MS in Biomedical Engineering from Tianjin University in 2008 and from Zhejiang University in 2011, respectively. Worked in National Instruments, Shanghai R&D as a software Engineer from 2011 to 2014. My current research investigates neural connections and coding properties within the brain for sound processing and plasticity. My research will also seek to develop and optimize ultrasound stimulation of brain and peripheral nerve circuits for treating various neurological disorders.


Mark Hamilton II

mhamilton Graduated in 2012 with a BS in Biomedical Engineering and in 2014 with a MS in Biomedical Engineering from Purdue University. My research will investigate the connections and function of the descending cortical network on ascending auditory processing and learning. My research will also seek to develop and optimize ultrasound stimulation of the descending cortical network to develop new strategies for treatment of tinnitus or hyperacusis.


Tianqi Li


Graduated in 2015 with a BS in Electronic Science and Technology from the University of Science and Technology of China. She is co-advised by Dr. Hubert Lim and Dr. Taner Akkin. Her current research is to characterize cochlear membrane vibration pattern in response to ultrasound neurostimulation in a guinea pig model by using optical coherence tomography. The final goal is to guide the development of novel ultrasound technologies for treating hearing disorders.


Gerardo Rodriguez

Gerardo Graduated in 2016 with a BS in Biomedical Engineering from the University of Utah. His research is focused on characterizing the effects of ultrasonic stimulation on the auditory pathway in a guinea pig model. Gerardo is also focused on developing a close-loop strategy based on Bayesian statistics and point process methods in order to treat hearing disorders.


Marti Westman

mwestman Graduated in 2017 with a BA in Speech-Language-Hearing Science and a minor in Neuroscience from the University of Minnesota. She is a first year student in the Doctor of Audiology (AuD) program.  She is currently working with Yezih on a human study of mSync, a non-invasive neuromodulation therapy for tinnitus.


John Basile


Graduated with a BS degree in Biomedical Engineering from Louisiana Tech University.  His research is to investigate novel ultrasound technologies and stimulation strategies for the treatment of hearing disorders. John's research includes safety studies in animal models of the developed therapeutic ultrasound techniques and his goal is then to test the safe techniques in humans for therapeutic value.                 


Maryam Hosseini


Graduated with a BS in Electrical Engineering and a MS in Biomedical Engineering. Her research focuses on understanding the neural representation of an auditory stimulus along with the encoding/decoding mechanisms of the mammalian brain. Her goal is to study background noise features that are transmitted to the higher structures of the auditory system. She was a visiting graduate student and is currently pursuing her PhD at the University of Sherbrooke.
