Homepage for Dirk Padfield

I am a Senior Research Scientist in image analysis working at Amazon in Seattle, Washington.  Prior to that, I was a Senior Research Scientist in the Biomedical Image Analysis Lab at GE Global Research in Niskayuna, NY from 2002 to 2014.  I work primarily in the area of image analysis, and my research interests include segmentation, tracking, classification, and registration algorithms.  In particular, I have extensive expertise 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.

Here is my resume/curriculum vitae (CV)

Here is a partial listing of my publications.


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