MD2K September Update

We are almost halfway through Year 2, and it’s very clear that the entire MD2K team has been busy! The first studies have been launched, and the center is approaching its first software release in December. Papers have been accepted and presented at multiple conferences as MD2K projects move forward. As we prepare for the MD2K Annual Meeting (Sept. 14-16), here is a rundown on the team’s accomplishments for the period between April 2015 and September 2015:

We have had two late-breaking news events this week:

Best Paper Award at MobiCom 2015
