In his research studies to develop new separation methods, Prof. Pesek has published over 230 scientific articles, while working with over 100 undergraduate students. Prof. Pesek will accept the award and present his work on March 20, 2018 at the 255th American Chemical Society National Meeting in New Orleans, LA.


Professor Bradley Stone Wins Jazz Award

Fall 2017

Prof. StoneProf. Bradley Stone has been recognized with the 2017 Bobby Jackson Award for Jazz Programmer of the Year (Internet and Non-Terrestrial Radio). The award recognized Prof. Stone’s programming and production of “The Creative Source” on SoulandJazz.com radio. The program champions radio airplay and greater exposure for new and current “living” artists and jazz composers. He has been the recipient of numerous awards for his work in jazz programming, including the prestigious “Duke DuBois Humanitarian Award” by JazzWeek in 2008, a national award for lifetime achievement and service to the jazz and jazz radio communities. Prof. Stone’s work at KSJS-FM at SJSU led to that station’s inclusion on the original panels for both the Gavin and JazzWeek national Top 50 jazz charts, as well as KSJS being selected as a 2-time winner (7-time nominee) of the JazzWeek “Jazz Station of the Year – Medium Markets” award.


Professor Madalyn Radlauer Joins Chemistry Department

Fall 2017

RadlauerProf. Madalyn Radlauer will be teaching courses in inorganic, polymer and general chemistry. As both an organometallic and a polymer chemist, she is looking forward to combining these two areas in her lab, studying small molecule catalysts in macromolecular environments. Like traditional organometallic chemists, students in her lab will synthesize catalysts to lower the activation barrier for challenging reactions relevant to the fuel economy, but these catalysts will then be appended to polymers. Thus, the small molecule catalysts will work as active sites within a larger scaffold, similar to a protein or enzyme. The polymers’ ability to alter catalytic activity will be explored, where we expect that this biomimetic approach will have significant effects.


Professor Ningkun Wang Joins Chemistry Department

Fall 2017

WangProf. Ningkun Wang will be teaching courses in biochemistry. With a background in protein interactions, Prof. Wang’s research combines biochemistry and biophysical methods to study indirect allosteric effects on the activity and substrate specificity of enzymes. The general goal of the lab is to study the “supporting actors” in biology that play a major role in the story and to learn how they go about doing that.

Specifically, the lab is interested in studying SIRT1, an enzyme that affects gene expression by de-acetylating transcription factors and histones.  SIRT1 has a large, unstructured N-terminus domain that is not directly involved in enzyme catalysis, but regulates the catalytic activity and substrate specificity. The lab will seek to elucidate the mechanism of this allosteric effect by studying the interactions between the N-terminus domain and the enzyme catalytic core.

Professor Chester Simocko Joins Chemistry Department

Fall 2016

Simocko lab membersThe chemistry department welcomes Prof. Chester Simocko to the department, where he will be teaching courses in organic and polymer chemistry. Prof. Simocko's research bridges the gap between organic chemistry and polymer science. He studies structure-property relationships in polymer systems by considering a desired property (mechanic strength, melting temperature, ion conduction, etc.) and determining how polymer structure affects that property. The lab controls polymer structure by growing a polymer from a surface to create polymer brushes and by making precise polymers and block copolymers for tailored self-assembly via alternating diene metathesis polymerization. Some of the students working on this effort in the Simocko lab are shown above: From left to right: Paul Abarquez, Sandy Rosa, Alexis Sarabia, Andrew Pham, Melvina Lu, Natsu Okuda, Bryan Chin (front), Josh Chen (back), Hamdy Yahya.

Professor Miller Conrad Awarded an NIH Grant to Investigate Resistance in Pseudomonas aeruginosa

April 4, 2016

Ken Choi and Sarah Matthews in the Miller Conrad labProf. Laura Miller Conrad was awarded an NIH SC3 Grant to investigate and block antibiotic resistance in Pseudomonas aeruginosa. The bacterium is the leading gram-negative cause of secondary infections in hospitals. Few treatments successfully clear the infection and resistant strains are increasingly encountered. One class of last-resort drugs currently used are cationic antimicrobial peptides (CAPs) like colistin and polymyxin B. Alarmingly, CAP-resistant strains have also been encountered, threatening the efficacy of these life-saving treatments.

The positively-charged CAPs enter the bacterial cell by electrostatic attraction to the negatively-charged outer membrane of P. aeruginosa, followed by disruption of the membrane. Once inside, the drug binds intracellular targets, killing the bacterium. In resistant strains, P. aeruginosa modifies its outer membrane to become less negatively charged, preventing uptake of the antibiotic. With the grant, the Miller Conrad lab will aim to inhibit a biosynthetic enzyme in the modification pathway, forcing the bacterium to maintain a negatively-charged outer membrane and to remain susceptible to CAP treatment. A successful inhibitor could be used in a combination therapy with the CAP antibiotic. Ken Choi and Sarah Matthews shown above are among the students working on the project.


Professor Rascón, Jr. Awarded an NIH Grant to Study Aedes aegypti Midgut Proteases

February 1, 2016

Members of the Rascon lab

Prof. Alberto A. Rascón, Jr. was awarded an SC3 research grant from the NIH. The project will investigate the role midgut proteases play during the blood meal digestion process in the virus-carrying Aedes aegypti mosquito. The mosquito specifically feeds on humans to obtain the nutrients needed for the egg laying process, and it is this blood-feeding behavior that facilitates the spread of blood-borne pathogens including Yellow fever, Dengue fever, Chikungunya, and the Zika virus, which has recently emerged in the Americas. At the moment, the only way to minimize pathogen transmission is through mosquito (vector) control. Current strategies include the use of insecticides, which have proven effective in reducing the mosquito population and slowing down pathogen transmission. However, there has been an increase in Ae. aegypti mosquito resistance to available insecticides and with increasing world population, global warming, urbanization, and the lack of other effective mosquito control strategies, the mosquito population will continue to grow. As a result, we will likely experience higher incidences of Dengue, Chikungunya, and Zika infections. The strategy being investigated in the Prof. Rascón, Jr. lab is to target the proteolytic enzymes involved in the blood meal protein digestion process, which should have a negative affect on egg development, reduce the mosquito population, and hence reduce pathogen transmission.

What Makes Dormant Seeds Germinate After Wild Fires?

August 15, 2012

Daniel StrausSeeds from certain fire-adapted plants can lay dormant for years until an intense fire causes them to germinate. Prof. Daniel Straus and his students have been studying the chemical signals from the fire that induce germination in these plants. Karrikins, small butenolides produced in the smoke of burning cellulose from plant material, have been found to be potent stimulators of germination. However, their isolation is tedious. Prof. Straus and his research student Jia Lu, have been using synthetic methods to produce karrikin and then testing the compound in field studies. Straus and his team have observed growth enhancement by their synthetic karrikin in one species, Ithuriel's Spear, so far. The advantages of producing karrikins by laboratory synthesis include the possibility of producing larger amounts and the ability to modify the structure. Prof. Straus is interested in exploring whether the known karrikins or analogues might have value as a growth enhancing agent in other plants, including crops. To learn more, see the article about their work in SJSU Today.

Light-Powered Artificial Enzyme Prepared

October 5, 2011

Light-powered artificial enzyme preparedGlobal climate change and the current economic crisis have stimulated interest in developing technologies utilizing renewable energy, such as sunlight, to avoid the dependence on fossil fuels. In a striking development in this area, Prof. Lionel Cheruzel's research group has developed a semisynthetic light-powered redox enzyme. The first generation of these enzymes are hybrids containing a photosensitizer covalently attached to a cytochrome P450 BM3 heme domain enzyme. Upon light activation, these hybrid enzymes catalyze the selective hydroxylation of long chain fatty acids. A preliminary account of their achievement has been published recently in a paper in Chemical Communications. Cheruzel and his coworkers are now engaged in preparing the second generation of hybrid enzymes with improved catalytic activity and substrate recognition.

Does Water Structure Matter?

February 1, 2011
Model of effects of secondary solutes on biological equilibria Yes! In a paper published in Biochemistry, Prof. Daryl Eggers describes a new phenomenological model for interpreting the effects of secondary solutes on biological equilibria, including protein folding. The model is based on the idea that changes in water structure, as induced by specific boundary conditions, are important because they reflect changes in the free energy of water. Co-existing subpopulations of water are related to a desolvation energy term that, in turn, may be used to explain the thermodynamic contribution of water to any aqueous reaction. Read Prof. Eggers' paper. An interview with Prof. Eggers, entitled “A New Perspective on Water,” was featured in the Winter 2009 issue of the alumni magazine, the SJSU Washington Square.

Modifying Materials and Cells with Fluorine

June 22, 2010
coating cell surfaces with fluorinated carbohydrates leads to reduced cell adhesionIt is well known that coating surfaces with fluoralkyl groups makes them both hydrophobic and lipophobic. The most well known example of this is DuPont polymer Teflon that can be used to generate an array of non-stick products from frying pans to stadium roofs. Now two research groups at SJSU have discovered that fluoroalkyl coatings can be used to significantly modify the surface properties of cells and chromatography materials. Prof. Joseph Pesek's research group recently published in Separation Science the finding that their newly prepared silica hydride-based fluorinated stationary phases have very promising retention properties for small hydrophilic analytes in aqueous normal phase HPLC. In a recent paper in the Journal of Medicinal Chemistry, Prof. Marc d'Alarcao's research group, in collaboration with Prof. Krishna Kumar's research group at Tufts University, report the finding that coating cell surfaces with fluorinated carbohydrates leads to reduced cell adhesion. This result may be important in the development of antimetastasis agents and diagnostic methods for cancer.


Undergraduate Student Goes to Germany for Research

June 2, 2010

Josh Young at work Josh Young, an undergraduate chemistry major at San Jose State University, traveled to Germany recently to help analyze the properties of silica hydride by nuclear magnetic resonance spectroscopy. Silica hydride, a unique material developed by the Pesek Research Group, has been shown to be more adaptable to the chromatographic analysis of samples ranging from simple organic compounds to large biological molecules than currently available commercial materials which are based on ordinary silica. Analysis of complex mixtures is essential for such fields as disease diagnosis, drug development, forensics, food safety and environmental monitoring. The new separation material, developed at San Jose State University, provides major benefits in all of these critical areas.  In Germany, Young studied the material by nuclear magnetic resonance in collaboration with Prof. Klaus Albert at the University of Tübingen. Practical applications of silica hydride are being developed by laboratories across the country and around the world.

Understanding Student Misconceptions

December 18, 2009
Symbolic drawing of chemical equationStudents studying general chemistry often develop misconceptions about the molecular details of the processes that they study. How can teachers prevent, or at least reduce these? In a recent paper published in the Journal of Chemical Education, Prof. Resa Kelly and her group begin to answer this question. In an NSF-funded study, Kelly's team examined student misconceptions about simple aqueous precipitation reactions by asking students to depict in drawings the molecular details of symbolic chemical equations. A careful analysis of the results reveals a range of misconceptions mainly dealing with misunderstanding the detailed meanings of the symbolic representations. These conclusions lead Kelly's group to make a series of recommendations for people teaching these principles.
