Objective To utilize my multidisciplinary experience in developing and implementing technology and products in materials science, photonics and optics based industry.
Education
As a member of Prof. Erramilli’s group in the ultrafast infrared spectroscopy laboratory, I worked on developing photothermal systems for materials characterization and biochemical detection. My focus was on establishing photothermal infrared spectroscopy and microscopy with IR quantum cascade lasers, establishing a new label-‐free technology for biochemical sensing and imaging.

I was a member of Infrared Spectroscopy Group at Photonics center under the supervision of Professor Shyam Erramilli. I worked on developing a label-‐free ultra-‐sensitive spectral-‐microscopy method for biochemical detection. It is based on the mid-‐infrared photothermal response induced by tunable high power lasers such as Quantum Cascade Lasers (QCLs).
§ Established mid-‐IR photothermal microscopy as a new technique breaking the diffraction limit. Investigating biological samples such as songbird brain pathology for studying the parts of the brain responsible for memory and learning.
§ Developed mid-‐infrared photothermal spectroscopy as a new label-‐free ultrasensitive technique for biochemical detection. § Established new plasmonic metamaterials for photothermal enhancement. § Engineered Infrared Plasmonic Metamaterials for Molecular Vibration Enhancement and Suppression Observed by Photothermal
Spectral-‐ Microscopy. § Developed a two-‐photon pump-‐probe photothermal experimental setup. § Performed optical, thermal and spectroscopic characterization of liquid crystals and showed the feasibility of using them for
photothermal spectral-‐microscopy studies. § Investigated nonlinear photothermal spectroscopy of nonlinear absorbers beyond spectral limits, which can lead to ultrasharp
resonances increasing sensitivity and spectral resolution. § Fabricated gold plasmonic metamaterial nanostructures on 𝑆𝑖 and 𝐶𝑎𝐹2 substrates for photothermal studies. § Investigated photothermal imaging on plasmonic metamaterials for enhancement and suppression of photothermal absorption. § Operated ultrafast femtosecond laser system for mid-‐infrared spectroscopy.
