Lechtreck Lab


Gehrig and Kiersten moving on.


After spending several terms as undergraduate researchers in the lab working on Chlamydomonas mutants, Gehrig Broxton and Kiersten Hilderhoff will graduate soon.

After 3 long years, our study on radial spoke assembly nears completion.

Happy New Year!  


Up to an icy start - temperatures in the microcope room fluctuate by up to 9 C! Main water pipe to science hill broke. Thank you President Trump for stopping global warming! Such a big button. The president appearently suffers from LMS (Liddle Man syndrome).  I can tell because I'm affected myself.  Karl


December 22: It's proceeding!


Peiwei Liu's paper on BBSome-dependent protein transport has been accepted in PNAS. Congratulations!

It's a laboratory Christmas with Jenna Wingfield's amazing model organism ornaments. 

Francesco Barbieri visits lab


We wecome Francesco Barbieri, a visiting Ph.D. student fromthe Lupetti laboratory at the Università degli studi di Siena, Italy.  Francesco will work on cargo transport by IFT trains using a combination of TIRF imaging and electron microscopy. The kymograms document the fixation of an IFT train (IFT20-mCherry, red) while transporting an outer dyein arm (IC2-NG, green).

Jenna Wingfield wins the poster presentation award at the Chlamydomonas 2016 meeting, Kyoto, Japan !



Karl Lechtreck presented data on outer dynein arm transport in flagella and chaired session No. 8 and Jenna Wingfield presented her prize-winning poster at the 17th International Conference on the Cell and Molecular Biology of Chlamydomonas (69th Yamada Conference) in Kyoto, Japan.

June 22: Batare Okivie moves on.


After a year in the lab, Batare Okivie leaves for Drexel Univesity, College of Medicine, pre-medical program, Philadephia. But not before having a farewell party and beiing celebrated for excellent lab work.  Her pet project, assembly and transport of radial spokes, will be taken over by Karl Lechtreck and Dr. Ilaria Mengoni. 

Lab-outing to the UGA Marine Institut, Sapelo Island, GA (May 6-8)




Together with the Gaertig lab (Jacek Gaertig, Mayukh Guha, Yuyang 'Patrick' Jiang, Panagiotta Louka) and students from the Eggenschwiler lab (Ashley Snouffer, Jonathon Walsh)

we visited the UGA Marine Institute on Sapelo Island for a 3-day science retreat.  Presentations by graduate studetns, postdocs,and technicians were mixed with beach time, bike rides, and cooking.

Welcome to our summer students


Heather Bomberger (Virginia Tech) and Aachi Kalra (Northview High School, Johns Creek, GA) spend the summer in the lab on research interships. 

Heather Bomberger, a sophomore in Biological Systems Engineering and minoring in Scieneering, participates in the NSF-sponsored REU program “Interdisciplinary Research Experience of Nanotechnology and Biomedicine” at UGA. Her project "Quantitative Analysis of Intraflagellar Protein Transport” is co-mentored by Dr. Peter Kner from UGA's College of Engineering.

Aachi Kalra participates in UGA's Young Dawgs programm, a high school internship program designed to prepare high-achieving high school juniors and seniors for post-secondary education and future careers in their areas of interest.  Aachi Kalra is interested in biomedicine; during her intership she will rescue the ift54-1 mutant using a GFP-tagged IFT54 transgene.


Congratulations !


Fiona Bell and Deep Patel, the first undergraduates to join the lab in 2012, have graduated.
