CV - David H Hagan
https://davidhagan.me/cv
Currently, I am a graduate student pursuing my PhD in Atmospheric Physics and Chemistry at MIT. My research is currently focused towards developing low-cost detectors for volatile organic compounds. Outside of the lab, I work as a software developer primarily in the areas of scientific computing and data acquisition. I am always looking for great contract opportunities for software gigs.

Tata Center Air Quality Project 2016-05-12T15:34:14Z. As part of my PhD and work with the Tata Center at MIT, I have been developing low-cost sensors for performing indoor and outdoor air quality measurements. I developed the hardware, firmware, and software, and currently have manufactured and deployed 10 units. Look for more updates in the near future! Py-openaq is a python API wrapper for the OpenAQ. Project. OpenAQ is building the first open, realtime air quality data hub for the world. The CTT Flask...

Growing Balls
September 10th, 2010 by Webmaster. It has been nearly four years now since Growing Balls. GB has been reviewed by my therapist colleagues (see The Therapist magazine, July/August ’08) and there is an itunes podcast link here. So, enough of an update; I hope perusing the site will entice you to get copy of Growing Balls. And see what it has to offer the young man making his way in society today. August 31, 2010.

And PhD student @MIT. I'm interested in understanding the lifecycle of secondary organic aerosol (SOA). Specifically, I am interested in the pathways taken throughout the atmospheric aging process of these particles in the atmosphere. Currently, I am working towards my doctorate at MIT, studying Atmospheric Chemistry and Physics. My current focus it designing low-cost, low-power sensors to detect and quantify trace atmospheric gases and particles.

Monday, August 31, 2009. Japan is an interesting proposition because of North Korean nuclear weapons, and its Taepodong series of long range missiles. Japan has begun to feel vulnerable. Forty-five years later that sentiment has not changed. That against the backdrop it only took about 8 kg of plutonium to make the Nagaski bomb. And against the backdrop of Japan's very strong missile program capable of sending objects into lunar as well as earth orbit. And against the backdrop of a statement thirty-five ...
