Research Summary : I am a Physical Chemist with interests centered in energy and the environment, particularly the free radical kinetic and mechanistic chemistry involved in environmental remediation of contaminated water systems, nuclear waste separation, storage, and remediation, and the biochemical mechanisms of carcinogenesis.
      - Total of 182 peer-reviewed publications (see also CSULB Publications)
      - 345 invited and student conference presentations
      - 11 current research students

  Research Interests: Environmental / Analytical / Physical Chemistry:
    My major research interests involve using physical and analytical techniques to  study free radical reactions in environmental chemistry, nuclear  chemistry and  (to a small extent) biochemistry.  Specifically I am concerned with with the  experimental study of kinetics, energetics, and  mechanisms of short-lived  (transient)  species such as ions, excited species and radicals in the aqueous  and the gas phases.
Some major specific projects that we are currently working on are:
       1) Advanced Oxidation Process remediation of chemically contaminated waters.  We are interested in using highly energetic radicals such as hydroxyl radicals, hydrated electrons, sulfate radicals  and chlorine atoms generated directly in water to remove chemical contaminants from treated wastewaters intended for reuse.(more)
       2) Chemistry of cancer.  Many chemicals are known or are suspected to cause cancer, however, their reactions and mechanisms under physiological conditions have not be determined. We are interested in how radical reactions are involved in these processes.(more)  
      3) Radiation-induced chemistry of ligands used in nuclear waste reprocessing.  We are currently investigating how alpha and gamma radiation degrade the ligands used in nuclear waste reprocessing (more)  
       4) Complexation kinetics of lanthanide ions in the aqueous and organic phase.  A new project we have just started is the kinetics of ligand complexation and decomplexation of lanthanide and actinide ions under solvent extraction process-scale conditions. (more)
