Ravi Shankar

Ravi is currently a PhD student in the ECE Department at JHU. Before joining JHU, he received his bachelors (B. Tech) from IIT Guwahati majoring in Electrical and Electronics Engineering. His undergraduate thesis was on keyword spotting and detection for low resource languages. His current research focuses on utilizing techniques tools from signal processing and machine learning to analyze and manipulate speech data. In particular, he is working on understanding what aspects of human speech affect its perception of emotion. Also, he is working on developing algorithms to morph speech between different emotions without changing its linguistic content. Ravi also enjoys playing tennis and soccer in his free time.


Evan Yu

Evan is currently a Master’s student in the BME department at JHU. He received his BS in Biomedical Engineering from The University of Texas at Austin (UT). His current project involves predictive modeling of Acute Kidney Injury (AKI) in cardiac surgery patients.
