Spring 2017

February 2017

Inaugural Herman D. Hughes Distinguished Lecture

The first SIMM of the spring semester will be held in March. However, we have a special treat for February as we kick-off the Herman D. Hughes Distinguished Lecture Series.

Reflections: Research Activities Involving High-Speed and Wireless Networks
Herman D. Hughes, Professor Emeritus of Computer Science & Engineering
Michigan State University

3:30 - 5:00
14 February 2017
Oliver Hall auditorium (room 112)


A brief description of the speaker's journey as a student, attending HBCU's to becoming a professor of computer science and engineering will be highlighted. Some emphasis will be placed on the Wireless and High-Speed research Laboratory (spearheaded by the Speaker) and its involvement in several activities. However, the primary focus of the talk will be centered around prior research on quality-of-service issues related to the transport of video traffic over ATM (autonomous transfer mode) Networks, Wireless ATM Networks, Wireless Ad Hoc Networks, and Network Workshops for Computer Science Professors from across the U.S.

About the speaker

Herman Hughes photo Dr. Herman D. Hughes (Doctor of Philosophy, Computer Science, 1973). Professor Emeritus at Michigan State University (Department of Computer Science and Engineering).

Dr. Herman D. Hughes, received a B.S. degree in Mathematics from Stillman College, a M.A. degree in Chemistry from Tuskegee University, and a Ph.D. in Computer Science from the University of Louisiana at Lafayette. He began his academic career as a high school mathematics teacher in 1959, followed by faculty positions in mathematics at Tuskegee University and Grambling State University. During his academic training, Professor Hughes worked in the summer months both in industry and government (IBM, American Oil Company, Dow Chemical, Advanced Avionics Research Lab). In 1973, Dr. Hughes joined the faculty of Michigan State University (MSU) as an Assistant Professor in the Department of Computer Science and Engineering. He climbed the academic ranks at MSU to become a Full Professor in 1984 and Professor Emeritus in 2005. While at MSU he also served as Assistant Dean of the Graduate School from 1986 through 1991.

Dr. Hughes became a national and international leader in the area of network traffic management and modeling with respect to wireless and high speed networks.
He designed several schemes for addressing quality-of-service issues central to recent network technologies, wireless ad hoc networks and Asynchronous Transfer Mode (ATM). The results of his research provided important insight for defining some key algorithms and parameters used by researchers for studying network traffic.
Dr. Hughes' work is published in numerous journals and has been presented at the most prestigious conferences. He served as a National ACM lecturer, and was voted Distinguished Alumnus both by Stillman College and the University of Louisiana at Lafayette. Professor Hughes' exemplary contributions to research, teaching and service earned him the MSU "Distinguished Faculty Award" in 2000.

Dr. Hughes' most recent research emphasis is quality-of-service (QoS) issues in mobile ad-hoc networks (MANET). Specifically, he has developed and published several
techniques and routing schemes designed to enhance QoS. From this work, he upgraded the high-speed networks and performances (HSNP) research lab to a modern wireless communication and high speed networks (WCHSN) lab.
After his retirement from MSU Professor Hughes relocated to Georgia.  He was appointed an Adjunct Professor in the Department of Electrical and Computer Engineering at the Georgia Institute of Technology where he is involved in research and consulting. He is affiliated with Georgia Centers for Advanced Telecommunications Technology, housed in the School of Electrical and Computer Engineering.

One phrase, two meanings: phytoplankton blooms in the coastal ocean
Beth Stauffer, Department of Biology, UL Lafayette

3:30 - 5:00
Tuesday, 15 November 2016
Oliver Hall auditorium (room 112)


Phytoplankton are the dominant primary producers in oceanic, lake, and coastal ecosystems, contributing approximately 40% of total carbon fixation on the planet and more than half of the oxygen in Earth’s atmosphere. In many parts of the ocean and for most periods of each year, highly diverse phytoplankton communities function as the base of aquatic food webs. These communities often undergo a spring “bloom” event, much like the greening of our terrestrial landscapes, which support productive food webs and fisheries throughout the world’s ocean. However, coastal phytoplankton communities can also “bloom” in a less productive fashion; these harmful algal blooms (HABs) have deleterious effects on food webs and higher animals (including humans) and appear to be increasing in both frequency and magnitude. This talk will explore the underlying causes of both types of blooms, compare their effects, and introduce some of the outstanding questions that new technologies are allowing us to begin asking.

About the speaker

Beth Stauffer photo Beth Stauffer joined the UL Lafayette faculty in January 2016 as an Assistant Professor in the Department of Biology. Beth earned her Bachelors of Science in Marine Science and Biology from the University of Miami (Go Canes!) and was awarded  her PhD in Marine Environmental Biology from the University of Southern California. Prior to joining the UL Lafayette faculty, she was a Lamont-Doherty Postdoctoral Fellow at Lamont-Doherty Earth Observatory of Columbia University and a AAAS Science & Technology Policy Fellow at the U.S. Environmental Protection Agency in Washington DC. Her research interests include phytoplankton ecology, biological oceanography, environmental technology, and water quality issues in coastal areas.

The Evolution of Deafness
Glen Watson, Department of Biology, UL Lafayette

3:30 - 5:00
Tuesday, 18 October 2016
Oliver Hall auditorium (room 112)


Hair cells are specialized for a mechanoreceptor function. Hair cells are critical to our ability to hear and maintain balance. In fish, hair cells in the lateral line system allow the fish to school and to orient in current. In sea anemones, hair cells are employed to detect swimming movements of nearby prey. Overstimulation of hair cells can result in lethal damage to hair cells in vertebrate animals. In anemones, overstimulation of hair cells activates a robust repair mechanism that depends in part on secreted proteins and protein complexes. Unfortunately, hair cells in vertebrate animals are less well protected by repair mechanisms leaving them vulnerable to succumb to damage after overstimulation. In mammals, lost hair cells are not replaced, leading to permanent sensory deficits. Interestingly, exogenously supplied 'repair proteins' from anemones can be used to treat experimentally traumatized hair cells in fish and in mammals. Such treatments result in significant recovery of the traumatized vertebrate hair cells. The therapeutic potential of anemone repair proteins will be discussed.

About the speaker

Glen Watson photo Glen Watson has investigated the sensory cell biology of sea anemones since 1984. He received a BS in Zoology from the University of Georgia, and a MS and PhD in Biology from Florida State University. Post-doctoral training was completed at the University of California, Riverside and at Loma Linda University School of Medicine. He came to UL Lafayette in 1989 as an Assistant Professor of Biology. Dr. Watson was Head of the Department of Biology from 2009-2012. Currently, Dr. Watson serves in the capacity as an Associate Dean in the College of Sciences and a Professor in the Department of Biology.

SIMM - September 2016

Be Careful: I can Read your Mind
Magdy A. Bayoumi, Center for Advanced Computer Studies, UL Lafayette

3:30 - 5:00
Tuesday, 20 September 2016
Oliver Hall auditorium (room 112)


This is one of the ultimate goals of the "Brain Initiative" which may be real by 2030. In general to be able to control our surrounding world by the power of our mind, to control the artificial limbs by our thoughts, and to read people's brain is a dream and it is an exciting one.

Brain Computer/Machine Interface (BCI/BMI) is one of the enabling technology towards these goals. We have designed and developed BCI chips that can overcome the main challenges of interfacing with human brain, mainly: low bandwidth communication, small chip area, low power and low heat dissipation, and tolerant to noise. This new chip is based on spike sorting. It is implemented in 0.5 um CMOS technology. Probably, the more reflective title of this talk is "Brain on Silicon". Finally, a case study of early prediction, warning, and detection of an epileptic seizure using the developed chip will be illustrated.
