Congratulations to Katie Vaeth, a co-mentored PhD student in my and Matt Taliaferro's labs, with successful defense of her PhD. She has done a phenomenal and trailblazing work on the role of RNA targeting to the midbody during cell division. Job well done Dr. Katie Vaeth!

NET1 mRNA localization to the midbody is required for ARP2/3-dependent initiation of mitotic abscission
The recruitment and activation of abscission machinery following mitosis is tightly spatiotemporally regulated, yet the underlying mechanisms remain poorly understood. We find that RNA localization an...

Ubiquitylation-dependent Rap2 activation regulates lamellipodia dynamics during cell migration - PubMed
Cell migration is a complex process hallmarked by front-to-back cell polarity that is established by the highly dynamic actin cytoskeleton. Branched actin polymerization creates a lamellipodium at the leading edge of the cell, while the contractile acto-myosin cytoskeleton is present at the lagging …

Not really. At the end you grant has to get a good score from study section that consists of independent scientists from various institutions. If your score is bad, you will not get funded no matter how well you know PO. Knowing PO may help you better understand what study sections are looking for.

It was a real pleasure to host Daniele Menjivar in my lab as part of CREU program (cancer research experience for undergraduates). It is such a breath of fresh air to be involved in mentoring new generation of scientists, especially in current anti-science environment.

Actually I completely disagree. Most of the Profs I know in our institution (men and women) are over-worked and under-paid (and stressed). They are expected to teach, bring grants, and do lots of administrative work.

What a sad news. Steve was an outstanding scientist and contributed greatly to midbody and centrosome biology. He was also a great colleague and an accomplished mountaineer. I will miss our scientific discussions and great hikes we did in Colorado. www.mercadantefuneral.com/obituaries/s...

For me it was that George Soros decided to fund me to come as exchange student (from Lithuania) to US. His decision to take a chance on me completely changed my life and eventually led to me getting a faculty position here at US.
