The LIMBS Laboratory has a new postdoc position available — see our Opportunities page.
On on Feb 9, 2016, Erin Sutton passed the dreaded Graduate Board Oral Exam…. Congratulations, Erin!!
Animals, including humans, routinely use movement to sense the world around them. For example, to sense the texture of an object, a person might move her hand over the surface, whereas to measure the object’s weight, she might hold it in her palm and move it up and down. This use of different movements to sense features of the environment is called Active Sensing. Although active sensing is commonplace in human behavior, how the brain generates and controls these movements is poorly understood. The goal of this project is to reveal and describe (in mathematical equations) the brain’s strategies for active sensing. This will be achieved by studying a specialized animal species, the weakly electric glass knifefish. This animal was chosen because it has a suite of properties that make it ideally suited for the experimental approach. The expected findings will have broad implications for active sensing in other animals (including humans) because active sensing behaviors are similar across species. This work will have broad societal impacts, including the possible transformation of robotic control systems and enhanced understanding of the brain that may ultimately improve our understanding of neurological disorders. Further this work includes multidisciplinary training of promising students in critical STEM fields.
How do you keep track of where you are as you walk through a known environment, such as your house or a shopping mall? To study this question, Mechanical Engineering professor Noah Cowan and Neuroscience professor James Knierim were selected to receive two awards that aim to use engineering approaches to shed new light on the brain’s “inner GPS”.
- 2015 Johns Hopkins Discovery Award, entitled “Engineering Approaches to Studying Spatial Representations in the Brain”. PI: Noah J. Cowan. $100,000.
- A National Institutes of Health R21, entitled “A Control Theoretic Approach to Addressing Hippocampal Function“, PI: Noah J. Cowan. $202,500.
On Thursday December 11 Alican Demir presented his PhD dissertation research to a packed seminar room at Johns Hopkins. Alican joined the lab as a Freshman in 2013, performed MSE thesis research in the lab, worked as a research specialist for a few years, and then completed his PhD, so his contributions have been monumental in shaping the LIMBS laboratory over the years. Congratulations Alican!
PhD candidate Mustafa Mert Ankarali has been selected to join the prestigious Siebel Scholars Class of 2015. This scholarship is awarded annually for academic excellence and demonstrated leadership to 85 top students from world’s leading graduate schools. Mert is the first Siebel Scholar from the Department of Mechanical Engineering at JHU.
LIMBS Lab Postdoc Sarah Stamper was awarded the International Society for Neuroethology’s Young Investigator Award. This prestigious award “… recognizes … early post-doctoral fellows who have shown outstanding promise and have already made a significant research contribution in neuroethology.” She will report her work in a special lecture at the ISN’s 2014 meeting in July in Sapporo, Japan.
LIMBS Lab postdoc Sarah Stamper placed third in the poster competition for the 1st Annual Johns Hopkins Postdoctoral Retreat on May 16, 2014. Sarah’s poster was on understanding communication and movement in groups of fish that live along the Amazon basin and use electrical signals for sensing.
