Hindle Lab

Updates from the Aerosol Research Group at VCU

2020 was challenging for all the obvious reasons, but we were able to return to work in July after our mandatory work from home period. [View Image]

Everyone in the lab has faced challenges over the past year, educating children from home, not being able to travel home to visit family and just dealing with the pandemic. Our annual lab celebration took place with pizza on a bench outside the Smith Building while we socially distanced. And I taught in empty classrooms.

But we have persisted and I am forever grateful for everyone’s support, enthusiasm and hard work in the last 12 months. Thank you, Amr, Mohammad, Serena, Nicole, Kelsey and Timothy, together with Dr. Longest’s team in Engineering and all our collaborators in the Golshahi, Xu and Heise labs.

Our projects continue to expand working on a new FDA contract with Drs. Golshahi and Longest together with an investment from the Bill and Melinda Gates Foundation

As we expand our research, we also continue to update our equipment, we now have a state of the art rheometer to characterize powder flow, the FT4 from Freeman Technologies. Last week, we installed our new powder x-ray diffractometer, the Rigaku Miniflex 600. [View Image]

Our publications continue to cover the scope of our research on powder formulation, device development, computational modeling and regulatory research.
