Please see below an opportunity for a postdoctoral fellowship in my lab at the NIH. We are looking for enthusiastic, talented scientists who will share our passion for microtubules and the beautiful world of tubulin diversity. Antonina *Postdoctoral Fellowship * *Cell Biology and Biophysics Unit, National Institutes of Health, Bethesda, USA* A postdoctoral fellowship opportunity is available in the Cell Biology and Biophysics Unit headed by Dr. Antonina Roll-Mecak to work on structural and functional studies of tubulin modification enzymes and molecular motors using a combination of X-ray crystallography, cryo-EM and single molecule fluorescence microscopy. Research in the Roll-Mecak lab focuses on deciphering the tubulin code ie how tubulin posttranslational modifications tune microtubule functions (see for instance Garnham et al., *Cell* 2015, Valenstein et al., *Cell* 2016, Vemu et al., *JBC* 2016; Zehr et al *Nature Struct & Molec Biology *2017). For more information about the lab please visit: https://neuroscience.nih.gov/ninds/rm_lab/ I am looking for enthusiastic, self-motivated Ph.D. graduates with a strong publication record and expertise in molecular biology, biochemistry, X-ray crystallography or electron microscopy who will welcome working in an interdisciplinary group with a supportive atmosphere and excellent resources. The Washingon DC area is a great place to live with great access to cultural and outdoor activities. Experience with assembly of protein complexes or structure determination by crystallographic methods or EM is a must. The successful applicant will be awarded a NINDS Intramural Fellowship.
