Brandeis Bio/Neuro. We study multiple aspects of sensory biology. Mostly in worms. Lab appears to be powered by vast quantities of junk food. Opinions mine.

Multiple postdocs out to academic/industry jobs + 2 grant NOAs in = open postdoc position. Worms are great to work with, sensory biology is an endlessly fascinating topic, and we are a group of good humans. Please email if interested!

Opening for a lab manager/Res Asst! This is a great position if you want more research experience (& perhaps co-author a paper or two!) before heading to grad school. We are a sociable, supportive, inclusive, and dynamic group - come join us.

RT @semilc: We thought there wasn't much new to learn about the cell cycle. Turns out we were wrong! Our paper (out today @Nature) identifiโ€ฆ.

TL;DR: IFT & cilia structure shape responses to stimuli sensed by a single neuron type in different & unexpected ways. Alison untangles this complexity by conditionally manipulating IFT & measuring response dynamics to individual chemicals. Questions/comments welcome! 6/6.

What about sensory response adaptation? By acute manipulation of IFT, Alison shows that IFT is needed for diacetyl but not pyrazine adaptation, likely by trafficking the diacetyl but not the pyrazine receptor. 5/6

So are cilia useless?! Well no ๐Ÿ˜…. Although odorant responses persist, there are desensitization & adaptation issues. Without IFT/cilia, odorant receptors mislocalize to branches from the cilia base, while the GRK-2 GPCR kinase stays in cilia, causing desensitization defects. 4/6

Completely unexpectedly, it turns out that w/o IFT, AWA shuttles many (but not all!) cilia-localized signaling molecules including odorant receptors to ectopic branches (arrows) that project from the cilia base. That allows odorant responses to be maintained even w/o cilia. 3/6

Alison used a ts kinesin allele that she generated (thanks to Chlamy ts screens!) to show that .a) IFT is not necessary to maintain cilia of the AWA olfactory neurons, & .b) even w/o cilia, AWA can respond to some food-related odorants. 2/6.

๐ŸŽ‰New lab preprint! ๐Ÿ”ฅ๐Ÿ”ฅwork by super postdoc @alison_marie1. C. elegans sensory neurons have gorgeous #cilia at their dendrite ends. Weโ€™ve always thought that a) no cilia = no sensory responses, & b) no IFT = no cilia. Punchline is we thought wrong. Read on for more. 1/6.

Woo-hoo! Go invertebrates and small (not necessarily 'simple' circuits and of course, go @betenoire1 and Gerry Rubin!.

Breaking a long silence on here to celebrate a few things: . Two postdocs have tenure-track job offers.Student's F31 funding approved.Student's paper accepted .My grant got a good score.AND.Our lab turns 28 today. Whew. (if anyone wants to do a postdoc w/us - please write!).

Friends - I have a three brand new codes available to the calmer bluer place. My bp stays low when I am over there. Steam does not come out of my nostrils. My head does not explode. If you want to come on over - DM or email me.

I am pretty much only over on the ๐Ÿ”ต site now but have 3 codes to give away if anyone is interested in moving over to a (as of now) kinder, gentler, less volatile space with no bots.

I think that when you are in a position of power and are a leader, it is really important to think about the impact of your words even if they represent your personal and not professional opinion. And for those asking, I resigned from @eLife back on Sep 1.
