   Who Am I ?

Google Scholar

I am a Human-Computer Interaction and Machine Learning researcher. I currently work at Sensel where we are creating the world's most advanced touch technology to revolutionize the way humans interact with the digital world. At Sensel, my research has been focusing on developing novel algorithms and features to build core competencies in the areas of accurate force sensing, precise touch tracking, and creating rich haptic experiences.

I received a Doctoral Degree in Computer Science from Texas A&M University, and I was advised by Dr. Tracy Hammond
. I was a member of the Sketch Recognition Lab where I was involved in the development of sketch, gesture, and activity recognition systems.

During my dissertation research, I developed gaze-assisted, multi-modal, accessible interaction methods for addressing impairments and disabilities. Also, using various machine learning models, I performed predictive analytics built on eye movements data applied to the domains of security, education, and economics.

Sensel, Inc. Sunnyvale, California

Designation

Senior Research Engineer. January 28th, 2019 - Present.

Nature of work

I am responsible for conducting research and development toward inventing solutions for human interface design to create and improve the world’s most advanced touch technology. My research has been focusing on building core competencies of Sensel in the areas of accurate force sensing, precise touch tracking, and creating rich haptic experiences. I work cross-functionally with engineering and design teams to integrate these novel technologies into consumer electronic devices such as laptop touchpads, automotive interactive surfaces, gaming peripherals, virtual reality, and so on.

I develop new algorithms and features to enhance touch and sensor performance across a variety of hardware and use-cases. Also, I am responsible for developing and evaluating new user experience concepts and prototypes that showcase Sensel’s force-sensing touch technology. Furthermore, to ensure that users have the best experience when using Sensel devices (e.g., touchpad), I design and conduct user studies to set the target accuracy and sensitivity metrics of the sensors. Lastly, to support mass production, I develop automated robotic tests that validate the quality of sensors.
