Here is a partial listing of my publications

I am currently working as a Staff Software Engineering at Google in the Research and Machine Intelligence organization.  I am designing machine learning speech recognition and language translation algorithms for on-device applications including seamless multi-lingual conversations, speech diarization, and continuous text transcription.  From 2014 to 2018, I worked as a Senior Research Scientist at Amazon.  I designed ML and image analysis algorithms for detecting and removing inappropriate and offensive images on the retail website.  I also served as a lecturer for the Amazon Machine Learning University.  Prior to that, I worked as a Senior Research Scientist in the Biomedical Image Analysis Lab at GE Global Research in Niskayuna, NY from 2002 to 2014.  I worked primarily in the area of image analysis, and my research interests include segmentation, tracking, classification, and registration algorithms.  In 2014, I also served as adjunct faculty at the Rensselaer Polytechnic Institute, teaching a class on biomedical image analysis.  I have extensive expertise in machine learning and in biological image analysis, inventing novel algorithms for segmenting and tracking cells and automatically analyzing their behavior.  In addition to microscopy and molecular pathology, I have worked on the medical modalities of Ultrasound, CT, MRI, and PET as well as industrial inspection and surveillance applications during my tenure at GE. 

I earned my Ph.D. in Computer Science in 2009 in the research group of Professor Badrinath Roysam at the Rensselaer Polytechnic Institute.

I earned my Master's in Electrical Engineering in 2002 in the research group of Professor William Higgins at
the Pennsylvania State University.

I earned
Bachelor's degrees in Electrical Engineering and International Studies in 2000 at the Pennsylvania State University.

Professional Service:

I am currently serving on the Steering Committee of the Transactions on Medical Imaging journal.  I am also serving on the organizing committee of the ISBI 2019 conference.  I also served on the organizing committees of ISBI 2015 and ISBI 2016.  I serve as a reviewer for a range of journals and conferences.


I was born in Alaska and moved with my family to Norway when I was a year old.  We moved back to PA 12 years later to be closer to extended family.  I completed a year of voluntary religious service at the Baha'i World Center in Israel before starting my undergraduate degree at Penn State.  For my second year of undergraduate work, I studied abroad in Egypt at the American University in Cairo where I focused on learning Arabic.  During the summer after completing my Master's degree in Electrical Engineering in 2002, I worked as a research scientist in Taiwan.  I currently live and work in Seattle, Washington.

I am a member of the Baha'i Faith. Here are links to the international and national (US) Baha'i websites.
