I work in the Cloud and Infrastructure Security Group in Microsoft Research, and my primary area of interest is using machine learning, artificial intelligence and signal processing for computer security. I am particularly interested in understanding how deep learning can improve computer security. In the past, I have also done research in the areas of audio signal processing, adaptive filtering, statistical signal processing, biomedical signal processing and wireless communications.
I earned my B.S. in Electrical Engineering from Auburn University, my M.S. in Electrical Engineering from the University of Colorado, and my Ph.D. in Electrical Engineering at the University of Washington.
At the University of Washington, Jim Ritcey, my advisor, and I developed a new method for evaluating the error performance for Direct Sequence / Code Division Multiple Access (DS/CDMA) communications of wireless channels including random or deterministic signature sequences. The new method could be used to model wireless channels include both fading and shadowing effects. I have also applied this method for the evaluation of outage probabilities.
Prior to transferring to Microsoft Research, I worked on audio for Windows and DirectX as a Senior Software Design Engineer. I helped ship Windows NT 4 – SP3, Windows 98, Windows 98 SE, Windows 2000, Windows XP and DirectX 7. Specifically, I worked on acoustic echo cancellation (AEC), 3D audio processing based on Head Related Transfer Functions (HRTFs), DirectSound, and porting the audio stack to use the Windows Driver Model (WDM) and Kernel Streaming (KS).
In addition, I have worked for the following organizations:
Senior Software Engineer, Siemens Medical Systems, Ultrasound Group, Issaquah, WA.
Senior Research Engineer, Physio Control Corp., Redmond, WA.
Applications Engineer, Motorola Inc., Digital Signal Processing Group , Austin, TX.
Teaching Assistant, University of Colorado, Boulder, CO.
Design Engineer, BDM Corp., Boulder, CO.
Summer Intern, Martin Marietta Corp., Denver, CO.
Cooperative Education Student, Intergraph Corp., Huntsville, AL.
Summer Intern, Computer Science Corp., Huntsville, AL.
