I am currently a PhD candidate working under the supervision of Dr. Margrit Betke and Dr. Stan Sclaroff with the Image and Video Computing research group at Boston University's Department of Computer Science. I attained a Master of Science degree in Computer Science from Boston University in 2014, and a Bachelor of Arts degree from Connecticut College in 2012 where I majored in Computer Science and Architectural Studies and completed a certificate program in Arts and Technology. I have had the opportunity to intern at Disney Research (Summer 2015) and Adobe Creative Technologies Lab (Summer 2016).
My broad research interests lie in the intersectional and interdisciplinary fields of computer vision, machine learning, and human computer interaction. Particularly, I am interested in the analysis of spatio-temporal human signals, generated for instance by eye-gaze, facial expressions and body gestures, in order to facilitate a computational understanding of various aspects of human behavior as well as enable intelligent interaction with the computer. In my spare time, I do freelance work in art and photography. Some of my work can be seen at ajjenjoshi.com.

"Goes in the pantheon of great CS TAs I've had here at BU." -CS440 student, Spring 2017
"Ajjen was the best teaching fellow I have had at BU thus far. He is very knowledgeable in all things computer vision and was helpful when explaining topics." -CS585 student, Fall 2014
"Ajjen is extremely qualified for this position and he clearly demonstrated it by helping students outside of class with projects he is not familiar with. He is extremely helpful and definitely deserves a good recommendation." -CS108 student, Fall 2013
