Mark Deimund, a senior in the Artie McFerrin Department of Chemical Engineering, has been nominated for the Marshall Scholarship, one of the two most prestigious and highly coveted academic scholarships available to United States students.

Deimund ’10 is from Oklahoma City. The president of Texas A&M’s American Institute of Chemical Engineers chapter, his recent research on biomass processing has garnered him a patent, and his current research involves systems biology in liver cells. He is also an avid strength trainer and enjoys classical literature. If selected as a Marshall Scholar, Deimund said he will study advanced chemical engineering at Cambridge University. He said he will also apply for the Winston Churchill Foundation Scholarship and the Gates-Cambridge Scholarship.

Deimund was recently named a 2009 recipient of the Craig C. Brown Outstanding Senior Award from the Dwight Look College of Engineering.

The Marshall Scholarship is tenable for two years of study at any university in the United Kingdom. Students must be graduating seniors or recent graduates and be nominated by the university. Hundreds of students from across the United States apply each year; only 40 of the approximately 1,100 who applied for the Marshall Scholarship in 2008 were selected as scholars.

Nominees will hear of their selection as finalists in the next one to two weeks. Finalists will then participate in regional or district interviews in Houston in November. The announcement of scholars will be announced shortly thereafter.

Texas A&M University has produced four Marshall Scholars, the most recent being Faye Hays in 2007. In the 2009 competition, biochemistry major Matthew Hickey was a finalist for the Marshall.

The Marshall Scholarships began in 1953 as a gesture of thanks from the British Government for the US assistance in rebuilding Europe after World War II. Former Marshall Scholars include Supreme Court Justice Stephen Breyer and New York Times Foreign Affairs columnist Thomas Friedman. According to the Marshall Scholarship Foundation, as future leaders, Marshall Scholars are “expected to strengthen the enduring relationship between the British and American peoples, their governments and their institutions. Marshall Scholars are talented, independent and wide-ranging, and their time as Scholars enhances their intellectual and personal growth. Their direct engagement with Britain through its best academic programmes contributes to their ultimate personal success.”

Because of the fierce competition for these scholarships, the preliminary process to be selected as an official university nominee is quite rigorous. Currently enrolled students and recent graduates should apply for selection in April, with the official deadline for the scholarships being in early October. To be awarded the university’s nomination, a student must show strong scholarly potential, demonstrated through their academic record and letters of recommendation from faculty, leadership ability, demonstrated through their involvement in student and civic organizations, and excellent speaking and analytical skills, as demonstrated in a series of interviews.

Once approved, prospective nominees can expect to spend months developing their applications as they work closely under the advice and guidance of faculty and academic advisors. The official announcement of university endorsement is made only after the nominees submit their finalized application to the scholarship foundations.

For more information, contact Kyle Mox, national scholarships coordinator in the Honors Programs office, at (979)845-1957 or kemox@tamu.edu.

Dr. Arul Jayaraman

Understanding how certain pathogenic bacteria strains such as E. coli cause infection in people begins with unraveling the complex “talk” between the trillions of cells living in the human gastrointestinal (GI) tract, says Arul Jayaraman, a Texas A&M University researcher who has developed an artificial system that mimics the unique bacteria-laden environment of the human GI tract.

The system is detailed this month in Lab on a Chip, a scientific journal published by the Royal Society of Chemistry, the largest organization in Europe for advancing the chemical sciences.

It represents a significant step in understanding bacterial interactions in the GI tract because it accurately simulates conditions within that area by enabling human epithelial cells to grow in balance with the naturally occurring bacteria (termed “commensal”) that reside in the GI tract.

Traditionally, growing both types of these cells simultaneously in a laboratory environment has been difficult because bacteria reproduce at a much faster rate than epithelial cells and tend to monopolize the nutrients needed by the epithelial cells, says Jayaraman, assistant professor in the Artie McFerrin Department of Chemical Engineering at Texas A&M University.

“If you try to achieve this in a cell-culture dish what happens is that you have a very nutrient-rich environment that bacteria basically thrive in, dividing rapidly,” Jayaraman says. “You can start with the same number of cells, relatively in proportion, but the bacteria will keep dividing, taking up all of the nutrients. Epithelial cells then do not get what they need. They are typically more finicky than bacterial cells. The numbers then kick in, and it is an exponential process where you will soon have millions of bacteria outnumbering epithelial cells, which will soon die.”

That doesn’t happen in Jayaraman’s model, which grows the epithelial and commensal cell colonies separately before allowing them to interact as they would in the gut. Once the two types of cells are interacting in the right balance, Jayaraman can recreate the sequence of events in a GI tract infection by introducing a foreign pathogen — in this case, enterohemorrhagic E. coli — to the cells within his model.

Previous studies have just added pathogenic bacteria into colonies of endothelial cells, but this approach does not replicate the cellular interactions and chemical signals present in the human GI tract, says Jayaraman, who holds the Ray Nesbitt Professorship at Texas A&M.

“If you really want to understand how the commensal bacteria that are in the GI tract either prevent or enhance infection, you need to have a way in which you can actually recreate the system with both components present – the commensal cells and the epithelial cells,” Jayaraman says. “To our knowledge, this is the first report describing co-culture of bacteria and epithelial cells and its application to investigate pathogen colonization and infection.”

Commensal bacteria, he explains, produce a wide range of bacterial signals, and the concentration of these signals in the GI tract is extremely high.

These signals, he adds, are given off during normal metabolic processes of the cells. While there is no evidence to suggest that they were created specifically for defensive purposes, some of these signals have evolved to act as a line of defense. Others may actually enhance a pathogen’s infectious potential, he says. For the invading pathogen, it’s a matter of “talking” to the right cells and avoiding the “wrong” ones.

It’s a game of “push and pull” that is further complicated by the fact that the strength of these signal levels varies, Jayaraman says. For example, a person may be under a lot of stress, which can cause stress hormones to be high and might in turn diminish the signals that aid in defense against a pathogen. Other times, a gastric disease might kill some of these cells that are emitting a protective signal, lowering the overall strength of the signal and making a person more susceptible to serious infection, Jayaraman notes.

So far, Jayaraman’s model has yielded some interesting findings, shedding light on the constant array of signals being emitted within the GI tract and their effects on invading pathogens. One of those findings reveals how indole, a chemical produced by commensal cells within the GI tract, acts a signal to foreign pathogens.

“Indole already has been shown as an important signal for communication between bacteria,” Jayaraman says. “We are looking at how pathogens might also be affected by indole, and we are seeing that they are indeed affected.”

Specifically, if a pathogen passes through bacteria that produce indole, the pathogen will become less infectious, Jayaraman explains. Conversely, if it passes through bacteria where there is no indole, the pathogen retains it same degree of virulence.

“In a sense, the pathogen is looking for weak points in a ‘wall’ of defense,” Jayaraman says. “We believe this can be applied to several other signals. There might be signals that increase a pathogen’s infectiousness. Does it choose a location in the wall where it can pass through without decreasing its infectious potential, or does it look for a place where its infectiousness is enhanced?”

Abraham Stroock, associate professor in the School of Chemical and Biomolecular Engineering at Cornell University, will discuss his research Wednesday (Oct. 21) as part of the 2009 J.D. Lindsay Lecture Series at Texas A&M University.

Stroock’s presentation, “Microvascular Structure and Function in vitro,” is scheduled from 3 to 4 p.m. in Room 106 of the Jack E. Brown Building. His presentation is sponsored by Texas A&M’s Artie McFerrin Department of Chemical Engineering.

Vascular structure — a network of convective paths — is a ubiquitous element in multicellular, living systems, Stroock said. The key function of vascular structure in animals and plants is mediation of convective mass transfer over macroscopic distances. This transfer allows an organism to monitor and control the chemical state of its tissues, he explains.

In Stroock’s laboratory, his research group is developing methods to embed and operate microfluidic systems within tissue-like materials in order to capture this function for both biological and non-biological applications. His presentation will detail examples of his efforts, including his experiments with “synthetic trees” in which he has reproduced the main features of transpiration.

After earning a bachelor’s degree in physics at Cornell, Stroock spent two years in France where he worked in the research division of Electricite de France and completed a master’s degree at the University of Paris VI and XI in solid state physics. Upon returning to the United States, he earned his doctoral degree at Harvard University and in 2003 joined Cornell as an assistant professor.

He is the recipient of the Henry and Camille Dreyfus New faculty award, the North American Mixing Forum Start-Up Award, the Office of Naval Research’s Young Investigator award, the 3M Non-Tenured Faculty Award, the Beckman Foundation Young Investigator Award, the NSF CAREER Award, and the Camille Dreyfus Teacher-Scholar Award. In addition, he has been named to MIT Technology Review’s TR35 list of top innovators under 35.

In honor of Professor J.D. Lindsay, Texas A&M’s first chemical engineering department head, the department established the Lindsay Lecture Series to bring speakers to the university. Coming from both industry and academia, the lecturers are recognized for their accomplishments in the practice, teaching and/or research of chemical engineering.
