The Chanda lab welcomes our two new undergraduate researchers in the lab! Stephan is a senior undergraduate in biochemistry and Owen is sophomore majoring in physics (and maybe mathematics, too). Both will be working with Ruohan and David on various aspects of the single-molecule projects in the lab.

Our new publication in Nature Structural and Molecular Biology is now online!  This study was led by Dr. Ana I. Fernandez-Marino and aided by a  fruitful collaboration with Dr. Lucie Delemotte lab at KTH Royal Institute of Technology, Solna, Sweden.  See the paper here.

After a semester study in Paris, Alex, an undergrad in the lab, has suffered enough with the wine and happily came back for the fascinating science (and beer). Welcome back Alex, we miss you!

Second collaboration between Ed Chapman’s lab and Chanda lab led by Huan and Debasis of Chapman lab gets to Nature. Yihao from Chanda lab helps with developing the single fusion pore recording. Fresh online, take a look!

It is bittersweet for the Chanda lab to say farewell to our  Dr. Marcel P. Goldschen-Ohm as he begins the next step in his career as an Assistant Professor of Neuroscience at the University of Texas-Austin! Marcel joined the Chanda lab in September of 2009 and has had many scientific accomplishments, specifically in the use of  single-molecule methods to probe ion channel gating. We wish the best with your new position. You will be missed!

Visit Marcel’s lab page here.

The Chanda lab is thrilled to welcome our newest post-doc, Ruohan Zhang! Ruohan comes from ASU where he did his PhD under Dr. Timoth Steimle using spectroscopic methods to study the rotational and vibrational structures of small metal-containing molecules in the gas phase. Ruohan joins David in being  jointly advised  between Baron and Randall Goldsmith and aims to use single-molecule spectroscopic measurements to reveal the dynamics of ion channels.

Welcome Aindrila!

The Chanda welcomes our new summer student, Aindrila Saha! Aindrila is a student through the Khorna Program and will be working with Claudia in the lab to studying the gating mechanisms of HCN channels.

 

Marcel Goldschen-Ohm has definitely been busy! Among writing many of his own papers, he found the time review a number many as well for the  Journal of General Physiology- more so than any other postdoctoral reviewer!  Here, JGP Editor-in-Chief Sharona E. Gordono presents Marcel with an award for  Postdoctoral Reviewer for Reviewed the Most Manuscripts in 2016 for the Journal of General Physiology.

Congratulations Marcel!

eLIFE Paper Published!

Co-first authors Marcel and Dima publish their paper in eLIFE where they combine single-molecule binding dynamics and a novel crystal structure to understand how cAMP binds to monomeric cyclic nucleotide binding domains of HCN2 channels. This also marks the first paper for both John and David from the lab! Congratulations all!

We bid farewell to our postdoc Ana over drinks and food at the Great Dane Pub! Ana will be starting a second postdoctoral fellowship in the lab of Kenton Swartz at NIH. We will miss you Ana and best of luck!

We are sad to see our undergraduate lab technican Zach leave but are happy to welcome his replacement, Natalie! Natalie is a first year undergraduate student in pursuit of biomedical engineering. Welcome Natalie!

Kevin has successfully defended his PhD thesis titled “Understanding the Gating Mechanisms of Voltage-dependent Sodium and Potassium Channels”. Kevin will soon be starting his new position at Ceullar Dynamics International with former Chanda lab member, Brian. Congratulations Kevin! You will be greatly missed!

David White has joined the lab from the Neuroscience Training Program and will be jointly-advised by Baron and Randall Goldsmith from the Department of Chemistry. Welcome David!

Hongbo Chen joins the Chanda lab as a co-advised student with Katherine Henzler-Wildmann. Hongbo will be using NMR to tease apart ion channel structure-function. Welcome!

Ming-Feng Tsai and Christopher Miller summarize our recent work as, “Chowdhury and colleagues report thermodynamics-inspired experiments that productively attack a long-lingering problem in sensory neurobiology: how certain ion channel proteins achieve the exquisite thermosensitivity that allows the neurons housing them—and us—to detect changes in temperature.”  Read more from Tsai’s commentary in “Building a Temperature-Sensitive Ion Channel.”

An introductory video on Linkage analysis by our collaborator, Dan Sigg. This video abstract accompanied two back to back articles in the Journal of General Physiology on the application of Linkage analysis to probe molecular basis of allosteric interactions.

The Journal of General Physiology published a video abstract for our lab describing how we estimate the free energy change for ion channels. This video relates to our article:
