Research Interests

  • Two photon excited fluorescence measurements of organic conjugated branched molecules and dendrimers. I am setting up the experiment and will be studying the relationship between structure and properties of these molecules. We have one of the world’s fastest lasers (20 fs pulses) in the form of an OPA that is powered by a regenerative amplifier (Spitfire-Pro). TPA has several interesting applications such as optical power limiting, 3-D optical data storage, imaging, photodynamic therapy and optical power limiting.
  • Synthesis and characterization of a water soluble poly(phenylene ethynylene). This involves a sequence of organic reactions (such as SN2 substitution) to synthesize two monomers and then couple them using Sonogashira-Hagihara chemistry to synthesize the polymer. Characterization will be done using NMR and GPC.
  • Processing and characterization of Polypropylene/Montmorillonite nanocomposites using a reactive twin-screw extruder.
  • Impact modification of Polypropylene/Montmorillonite nanocomposites; comparison between a polymeric elastomer and an oligomeric, functionalized elastomer.
  •  Processing PMMA/Laponite nanocomposites for enhanced hardness, scratch resistance and superior barrier properties. A key feature of this work was that the transparency of PMMA was not sacrificed. Effect of clay loading on PMMA was also studied.
  •  Nanocomposites from Polycarbonate and nano-sized ferrite particles based on Ni, Fe and Zn were synthesized for imparting magnetic properties to PC. All processing was done using a reactive twin-screw extruder.
  •  Have also helped with reactive processing for recycling cell phones. In this project, funded by Motorola, the housings were separated from metallic components and then the plastics were attempted to recycle using reactive processing.

Research Interests

  • My research project is focused on the design and synthesis of novel chromophores for application in the study of peptide aggregation through the utilization of ultrafast laser spectroscopy. Synthetic organic chemistry is being used to synthesis a biologically compatible chromophore, structurally similar to that found in GFP, which possesses strong two-photon emission (TPE) characteristics suitable for spectroscopic study using ultrafast laser systems and non-linear spectroscopy. The TPE of the synthesized chromophores are being characterized, investigating their fluorescence quantum yields and cross-sections for the purposes of determining their viability as biological probes. The chromophore will be attached to a peptide segment of α-synuclein or other interesting peptides and spectroscopic techniques will used to perform a detailed investigation into the aggregation properties of the peptide systems using a combination of circular dichroism, two-photon excited fluorescence up-conversion, time-correlated single-photon-counting, and near-field scanning optical microscopy.Dr. Travis Clark is currently a post-doc at the University of Chicago under Professor Luping Yu

Biography

As a student researcher in the Goodson Group, I am working on two projects. My first project involves the physical characterization of a calmodulin-attached fluorescent probe that is activated upon calcium-binding. I have utilized two-photon spectroscopy to map out two-photon cross-sectional changes at different sites of fluorophore attachment. I will use NSOM (near-field scanning optical microscopy) to examine the fluorescent properties of the calmodulin system on a mica surface. My second project involves the physical characterization of light-harvesting organic polymers. I have utilized two-photon spectroscopy to measure cross-sectional changes due to tuning of the HOMO-LUMO band gap and ultra-fast time-resolved fluorescence spectroscopy (up-conversion) to understand mechanisms for fluorescence decay.

Previous research experience in a physiology laboratory studying asthma pathogenesis, biochemical mechanisms underlying asthma exacerbations, and glucocortocoid effects on rhinovirus-induced inflammation.

    Franco Fabiilli

    Undergraduate Student

    Hello, my name is Franco Fabiilli and I am a junior at the University of Michigan. I am completing my bachelor’s degree in chemistry. This past summer, I worked on a project examining the dielectric behavior of novel organic-metallic and organic-inorganic composite materials. These types of materials have possible industrial use in high frequency application capacitors. I have also been a mentor for Project SEED, a program through the American Chemical Society that exposes high school students to areas in science and engineering. This fall, I am working on publishing my results from the summer term. Outside of chemistry, I am a trumpet player in the Michigan Marching Band as well as an active swimmer.

    Academic History

    Dr. Andrew Callender received his B.S. in chemistry and biology from King College (Bristol, TN), then moved to the University of Michigan. He worked with Prof. Mark Meyerhoff on the electrochemical synthesis and characterization of porphyrin-based conducting polymers as a stationary phase for HPLC, completing the M.S. degree in 2003. His Ph.D. research (2006) was conducted with Prof. Michael Morris, focusing on the development of techniques and instrumentation for high-speed dynamic Raman microspectroscopy of bone tissue. His primary research interests are in the application of novel materials to analytical chemistry; currently this involves the development of materials with unusual optical properties.

    Research Interest

    • In the area of nonlinear optics, organic multi-chromophore systems such as carbon networks composed of repeat building block molecules  have been utilized for two-photon absorption (TPA) effects ,which may have applications in optical limiting, imaging, and photodynamic therapy.
    • We analyze the determining factor which governs the magnitude of the cross section of these systems.
    • I’m investigating two samples with a wide range of molecular symmetries so as to figure out a new avenue toward increasing the two-photon cross section with identical building block chromophores.
