Your Image

Hi, I am a passionate and driven Ph.D. student in Computer Science at SCAI, Arizona State University. My research focuses on creating innovative technologies for assisted living and sports through the intersection of computer vision and human-computer interaction. I have had the opportunity to collaborate with partners from notable companies such as FedEx, Pizza Hut, Adidas, Amazon, and Edgenuity to solve real-life problems in data science, augmented reality, and human-computer interaction. As a lead researcher in the iLUX and ANGLE labs at ASU, I had an opportunity to guide undergraduate and graduate students in a variety of projects involving application development, data analysis, and data science. My expertise in affective sensors such as ECG - Electroencephalography, GSR - Galvanic Skin Response, Eye Tracking, and Facial Emotions, as well as my experience in using Microsoft HoloLens for developing educational and tutoring augmented reality applications, makes me a valuable resource in usability testing research in a variety of environments. I have been awarded two grants including the WearTech Grant and Global Sport Institute Grant, as well as being an NSF Research Trainee for Citizen-Centered Smart Cities and Smart Living. I also first-authored multiple papers in reputed journals and have co-authored a patent. I also have a very good track record of teaching, leadership, and mentoring. My excellent knowledge of HCI and computer vision combined with my contagious passion for research and teaching, make me a valuable addition to any team.
