- Research Associate, Sana Chaudhry, has 'retired' from the lab to begin graduate school in the PIBS program at UM's Miller School of Medicine. We will miss her terribly, but knowing we can still see her around makes that easier to take. Best of luck in your new adventures!!
- The reviews for Bhavya Ravi's GOA-1 paper submitted to J. Neuroscience came back. Where we can, we are working to revise the manuscript to address the issues the reviewers have raised.
- The lab has begun limited resumption of research activities through creative scheduling, social distancing, and obligatory wearing of masks and sanitation of shared equipment. It's not ideal, but hopefully we will grow comfortable in this new normal.
- The lab remains in COVID-19 shutdown. We've been told that lab personnel can return at reduced density in June, so hopefully we can return to research activities shortly.
- A revised version of Bhavya's GOA-1 manuscript has been submitted to J. Neuroscience based on feedback we received from the reviewers at eLife. A pre-print is available on BioRxiv.org. Fingers crossed for a relatively painless review.
- Former Ph.D. student Bhavya Ravi was awarded 4th place in the 2019 UM Medical Faculty Association’s Best Research Award! The award comes with a $500 cash prize and a trophy. Kevin thinks he nominated Bhavya for this back in 2018, but better late than never. Congratulations, Bhavya!
- Kevin heard that the UM Board of Trustees accepted recommendations from the Dean, Provost, and President to approve his promotion to Associate Professor with Tenure, effective June 1, 2020. Whew!
- Lab remains in COVID-19 shutdown. Everyone is trying their best to work from home and to stay healthy.
- Due to COVID-19, we have suspended non-essential in-lab research activities. Lab members are doing their best to work from home: reading papers, performing data analyses, completing manuscripts, etc. Hopefully such social distancing measures will be sufficient to flatten the curve of viral transmission, and we can get back to research soon.
