CSEE professor Gymama Slaughter talked about her research to develop an implantable glucose sensor powered by chemical reactions in the human body at TEDxBaltimore in January. In her work in the UMBC Bioelectronics Laboratory, Slaughter concentrates on how chemical processes occurring naturally in the human body can power medical devices and eliminate the need for batteries in devices like blood glucose monitors. “If we could only remove batteries from the equation,” said Slaughter, “all of a sudden, we would have truly wearable and implantable sensors.”

UMBC CSEE Seminar

A Neural Circuit Deconvolution Approach to Study Motivated Behavior

Dr. Joseph Cheer

and Department of Psychiatry
School of Medicine, University of Maryland Baltimore

11:001am-12:00pm, Wednesday, 3 February 2016, ITE 325b

In order to examine relationships between subsecond dopamine signaling and nucleus accumbens (NAc) cell firing during reward-directed behaviors, the ideal experimental approach is to record postsynaptic neuronal firing from the same electrode used to measure dopamine release. We have demonstrated that these measurements are feasible using cylindrical carbon fiber electrodes that can voltammetrically detect the oxidation potential of dopamine and also measure single-units extracellularly or local field potentials (LFPs). Moreover, we have added iontophoresis barrels to the carbon-fiber microelectrode to allow localized, rapid drug delivery to examine the signal transduction utilized by postsynaptic neurons when dopamine release is detected. The drugs to be ejected out of the iontophoresis barrels are selected on the basis of effects of prior microinjections (such as dopamine receptor antagonists). Once a significant behavioral effect is observed following the microinjection, iontophoresis pipettes with the same compounds are loaded for ejection in other animals. Under these conditions ongoing behavior is unaltered allowing for a detailed neurobiological dissection of the particular microanatomical domain during specific times of the behavioral sequence. Finally we can now provide causality between the two simultaneously recorded measures, by applying the above mentioned to animals amenable to optogenetic interrogation of dopaminergic pathways. We will show that dopamine sculpts cue-related patterned neuronal activity as well as the power of the NAc LFP during reward seeking.

Dr. Joseph Cheer graduated from Universidad de los Andes (Bogota, Colombia) with a B.S in Biology and Mathematics in 1996. He joined the Laboratory of Neurobiology and Experimental Microsurgery at the Colombian Neurology Foundation where he worked for 1 year investigating CNS regeneration using oncogene-tranfected cells and sciatic nerve co-grafts in motor cortex-lesioned animals. Joe received his Ph.D from The University of Nottingham (Neuroscience Section of the School of Biomedical Sciences) under the direction of Profs Charles Marsden and Dave Kendall and Dr Rob Mason. Dr. Cheer’s graduate research focused on the behavioral and electrophysiological effects of cannabinoids.

Dr. Cheer’s first postdoc (2000-2002) was spent in Sam Deadwyler’s laboratory (Wake Forest University School of Medicine) where he conducted research on multiple single-unit electrophysiology in freely moving organisms. Joe joined Mark Wightman’s lab as a post doc in fall 2002 at the University of North Carolina (Chapel Hill). There, he established the use of a microelectrode that allows for the simultaneous measurement of single-unit activity and dopamine release via fast-scan cyclic voltammetry.

Dr. Cheer is currently a tenured associate professor at the University of Maryland School of Medicine, where he directs several NIH and private foundation-funded graduate and undergraduate projects related to several neurophysiological and neurochemical aspects of endogenous cannabinoid signaling in intact systems.

Big Data/Data Science Programs at NSF

Chaitan Baru
Senior Advisor for Data Science, NSF CISE Directorate
10-11:00am Thursday 28 January 2016, ITE 459, UMBC
postponed

This talk will provide an overview of current programs and activities related to Big Data and Data Science at NSF, and also highlight NSF’s inter-agency engagements in this topic area. The talk will also discuss future directions for Data Science research, education, and infrastructure. Considering that Data Science is a rapidly emerging, evolving field and discipline, ample time will be provided for Q&A and discussions about where the field ought to be going, given what we know today.
Dr. Chaitan Baru is currently a senior advisor for data science in the Computer and Information Science and Engineering Directorate at the National Science Foundation. He is a Distinguished Scientist and Associate Director of Data Initiatives at the San Diego Supercomputer Center (SDSC), UC San Diego where he works on applied and applications-oriented research problems related to data management and data analytics.

Dr. Baru has participated in a number of “data cyberinfrastructure” initiatives, including as Principal Investigator of the OpenTopography project; Cyberinfrastructure Lead, Tropical Ecology, Assessment and Monitoring network; Co-Investigator of the Cyberinfrastructure for Comparative Effectiveness Research project; Member of the founding Senior Management Team of the National Ecologial Observatory Network and Co-PI of the NEON Cyberinfrastructure Testbed; Co-PI of the CUAHSI Hydrologic Information Systems; Director, NEES Cyberinfrastructure Center; PI/Project Director, Geosciences Network; and member of the How Much Information? project.

Baru leads the Advanced Cyberinfrastructure Development Group at SDSC and is also Director of the Center for Large-scale Data Systems research. Prior to joining SDSC in 1996, Baru was at IBM, where he led one of the development teams for DB2 Parallel Edition Version 1 and at the University of Michigan, where he served on the faculty of the EECS Department. He received his B.Tech in Electronics Engineering from the Indian Institute of Technology, Madras, and M.E. and Ph.D. in Electrical Engineering from the University of Florida, Gainesville.

Registration for the 2016 Global Game Jam is open!

UMBC is once again hosting the Global Gam Jam this January. It will run from 5pm Friday, January 29th to 5pm Sunday, January 31st, just after classes start. Space is limited, so sign up now!

For anyone who hasn’t participated, the global game jam is a 48 hour game development event with hundreds of host sites around the world. At 5pm local time, introduce the jam and announce this year’s theme. Previous year’s themes have ranged from a phrase (“as long as we’re together there will always be problems”) to a word (“extinction”) to an image (ouroboros: a snake eating its tail), to a sound (the recording of a heartbeat). Participants brainstorm game ideas around the theme, form into teams, and spend the weekend building games that are designed to be both fun and express the theme.

The UMBC site is not restricted to just students. In previous years, we have had a mix of UMBC students, alumni, students from other schools, game development professionals, and just people with an interest in game development. More details at gaim.umbc.edu/global-game-jam. However, we are limited to just 40 participants, so sign up early if you want to come. If UMBC fills up, other local(ish) sites include the Universities at Shady Grove and American University. If you are not near UMBC, check the Global Game Jam for a site near you.

This past weekend, Dr. Rick Forno, CYBR GPD and Assistant Director of the UMBC Center for Cybersecurity, joined Dr. Matt Blaze (UPenn), Dr. Jeff Foster (UMCP), and COL (Ph.D) Greg Conti (USMA) on the closing plenary panel for Schmoocon 2016 in Washington, DC.

ShmooCon is an annual east coast hacker convention offering three days of an interesting atmosphere for demonstrating technology exploitation, inventive software and hardware solutions, and open discussions of critical infosec issues.  The first day is a single track of speed talks called One Track Mind.  The next two days bring three tracks:  Build It, Belay It, and Bring It On.

The panel examined the current state of information security programs in academia. Along the way they discussed issues around dealing with administration and the peculiarities of information security, the current state of information security research, attracting and vetting students/faculty, and generally what it’s like to be growing the next generation of information security professionals in a time where academia frequently is placed in the position of “building the bus while going down the road.”
