Some of the projects listed here involve collaborations with researchers affiliated with the Center for Environmentally Beneficial Catalysis.  The collaborators are reflected in the list of representative publications.

Catalysis with Gas-Expanded Liquids:  We have exploited the pressure-tunable properties of gas-expanded liquids (GXLs) in a variety of catalytic systems. At ambient temperatures, gases such as carbon dioxide (CO2) and light hydrocarbons (such as propylene and ethylene) are close to their critical temperatures.  When mildly compressed (to tens of bars) at such temperatures, they dissolve in most conventional solvents and volumetrically expand them. The increased free volume of the GXL phases accommodates permanent gases such as O2, H2 and CO in unusually high concentrations. We have harnessed these unique properties to demonstrate several novel GXL-based catalytic reaction engineering concepts.  These include (a) highly selective hydroformylations at mild conditions;(b) inherently safe ethylene epoxidation process that eliminates CO2 formation as a byproduct; (c) formation of high purity terephthalic acid with reduced solvent burning and carbon footprint; and (d) Facile CO2 electrochemistry in CO2-expanded electrolytes.

Engineering Micronization and Coating Applications with Dense Phase Carbon Dioxide:  Particle micronization with supercritical carbon dioxide (scCO2) allows for reproducible crystal formation with the potential for increased surface area (hence enhanced dissolution rates) and concomitant sterlization. Coating with dense phaseCO2 allows the use of traditional organic soluble coatings with complete solvent recovery and virtually no atmospheric emissions. Specific products developed using these processes include taxol nanoparticles (Nanotax®), insulin nanoaggregates, polymer-coated stents, lyophilized drugs, etc.). These technologies have been licensed to a startup company (CritiTech, http://www.crititech.com/).  The Nanotax® anticancer drug produced using this technology is now undergoing clinical trials in the U. S. to treat a variety of cancers. 

Metal-exchanged Mesoporous Silicates with Tunable Properties: Emerging feedstocks from biomass and natural gas liquids (NGLs) provide unique opportunities for catalyst development. For example, catalysts that are composed of earth-abundant materials are desirable to process feedstock molecules ranging from NGLs (C1-C5) to bulky biomass-based molecules (C18+). We have synthesized metal-exchanged mesoporous silicates that are highly tunable with respect to acidity and may be synthesized to accommodate a wide range of pore sizes (2-9 nm). We have incorporated metals such as Ce, Zr, W and Nb, into mesoporous silicates such as MCM-48, KIT-5, KIT-6, SBA-16 and TUD-1 using single-pot techniques. The metal-exchanged silicates show remarkable activity for a variety of chemical transformations, including Friedel-Crafts alkylation, Meerwein–Ponndorf–Verley (MPV) reduction, Prins cyclizations, olefin metatheses and lignin depolymerization.

Intensified Processes with Ozone:  Ozone is apowerful oxidant that can activate C=C and C-H bonds at ambient temperatures to produce valuable chemical intermediates.  The main challenges in ozone-based chemical transformations are to (a) manage energetic intermediates safely, (b) stabilize the intermediate products from over-oxidation, and (c) develop solvents that are relatively inert to ozone and promote reaction pathways that do not form energetic intermediates. We have demonstrated novel media (such as liquid CO2) and reactors (including spray reactors) to enable safe and intensified chemical transformations with ozone to produce value-added intermediates and materials.  Examples include continuous ozonolysis of fatty acid methyl esters in liquid CO2,  spray ozonolysis of lignins to produce flavoring agents (vanillin and 4-hydroxybenzaldehyde) and highly selective alkane oxidations.  We are developing modular ozonolysis reactors for distributed manufacturing involving biomass and shale gas feedstocks.

  • Multiphase Reactor Engineering for Safe and Intensified Oxidations


Creative solutions to engineering problems require a sound complement of fundamental knowledge, intuition, imagination and critical thinking. I believe that a teacher has a vital role and challenge in fostering these attributes in students. My teaching methods are aimed at achieving this goal. In the theory courses, I show how engineering equations are essentially 'math-based languages' or models that aid our understanding of physical and chemical processes. I constantly encourage students to assess if the process behavior predicted by the model makes intuitive sense. Given that commercial software is invariably used for equation-solving and design purposes, it is especially essential to develop such an understanding and intuitive feel for interpreting results from computer simulations. I provide examples of how theories and equations have been used to develop engineering solutions in everyday life. In addition to traditional homework assignments that emphasize fundamentals and solution procedures, I assign two to three open-ended projects that are comprehensive in nature. These projects address industrially important problems and require students to integrate fundamental knowledge, intuition and imagination in critically analyzing and designing sustainable engineering processes that are resource-efficient (i.e., conserve feedstock and energy). I emphasize how resource-efficient technologies not only make good business sense but also are inherently green.

I believe that the laboratory courses provide a vital forum for not only reinforcing theoretical concepts but also developing essential experimental, data analysis, troubleshooting, team work and communication skills. The analysis/interpretation of experimental data form the basis for the preparation of various types of written reports (journal-type, memos, etc.) and oral presentations. Prior to each laboratory session, I require student teams to make concise presentations about their planned work and to rigorously defend their work plan. Besides providing training in oral and written communication skills, this process also helps students to solidify their understanding of theory.

Clear statement of course goals and expectations, effective lectures and notes, challenging yet fair assignments and tests, and accessibility to students are all essential to a positive learning experience -- one that motivates students' desire to learn and to excel. My teaching methods continue to evolve as I have learned more about teaching tips and techniques from student/peer feedback and from periodicals such as the Teaching Professor and Chemical Engineering Education, especially those that use modern technology-based classrooms to deliver instruction in novel ways.

My major teaching interests are in the areas of chemical engineering kinetics, reactor design, industrial development of sustainable catalytic processes, transport phenomena, mathematical methods in chemical engineering, and supercritical fluid technology.

Teaching interests:

  • Chemical engineering kinetics and reactor design
  • mass transfer
  • mathematical methods in chemical engineering
  • industrial development of sustainable catalytic processes
  • chemical engineering unit operations laboratories
  • undergraduate and graduate courses.

I have been active in service at both the University of Kansas and the professional societies [American Institute of Chemical Engineers (AIChE) and the American Chemical Society (ACS)]. I especially like roles where I am able to contribute to transformational changes that have long-term beneficial impacts on the institutions I serve.

I have served as graduate advisor of the chemical and petroleum engineering (C&PE) department to streamline graduate advising, curricular and graduate recruitment activities. Later on, I served as department chair when the C&PE faculty implemented a five-year strategic plan with positive outcomes including the creation of a NSF engineering research center [the Center for Environmentally Beneficial Catalysis, CEBC], increased external research funding, the addition of five new faculty lines for interdisciplinary initiatives in the areas of catalysis and bioengineering, and the successful mentoring and nominations of several faculty for teaching and research awards.

As CEBC director, a unique industry partnership program was implemented. In partnership with member companies (that have included ADM, BASF Catalysts, BP, ConocoPhillips, Chevron Phillips, DuPont, Eastman Chemicals, Evonik, ExxonMobil, Grace, Invista, Procter&Gamble, Novozymes, Reliance Industries, SABIC, SI Group, and UOP), the CEBC is developing and providing licensing opportunities for novel sustainable technologies related to fuels and chemicals.

Since its inception, the CEBC has launched several multidisciplinary research initiatives dealing with sustainable catalysis for producing fuels and chemicals with funding from federal, state and industry sources. The total funding from these sources is nearly $60 million since 2003, resulting in ~450 publications, 60 inventions, 18 patents, 6 licensed technologies, nearly 70 advanced graduate degrees, >50 postdoctoral researchers mentored and >50 undergraduate researchers trained. These successes have also resulted in the addition of several faculty members in the chemistry and C&PE departments. I chaired the recruitment of several of the current C&PE faculty members in the areas of catalysis, reactor engineering and materials science. I serve as mentor to several of the young faculty members recruited as part of these initiatives.

For nearly two decades, I have been active in external professional service focused on facilitating sustainable practices in the chemical process industries, including the use of biomass as a renewable feedstock to produce chemicals and fuels. I have served on several national and regional technical panels including the NSF/EPA panels on environmentally benign processing, and the Midwest Biomass Research & Development Initiative Roadmap panel. I served as the President of the International Symposia for Chemical Reaction Engineering (ISCRE, Inc.) during 2011-2012, and on the Board of Directors of the Organic Reactions Catalysis Society (ORCS) from 2010-2018. I am one of the founding members of the Great Plains Catalysis Society (GPCS) initiated in 2017 and currently serve as the Secretary of the organization.

I have served on the scientific and organizing committees of several international symposia in catalysis and reaction engineering, co-chairing the 18th International Symposium on Chemical Reaction Engineering (ISCRE-18, Chicago, 2004), the 2nd North American Symposium on Chemical Reaction Engineering (NASCRE-2, Houston, 2007) and the 2nd and 3rd Joint India-U.S. Chemical Engineering Conference on Energy and Sustainability (Chandigarh, 2008; Mumbai, 2013). In 2018, I chaired the Gordon Research Conference on Green Chemistry held in Barcelona, Spain.

I currently serve as Executive Editor of ACS Sustainable Chemistry and Engineering, a relatively new ACS journal launched to archive research advances in sustainability-related research in the chemistry and chemical engineering disciplines. I also serve on the editorial boards of Industrial and Engineering Chemistry Research (past), Applied Catalysis B, Canadian Journal of Chemical Engineering, and Chemical Engineering Technology.
