SAS Early Career Interest Group


About Us:

In 2021, the Society for Applied Spectroscopy (SAS) created an Early Career Interest Group (ECIG) and membership category to serve scientists who have graduated with their final degree (bachelors, masters, or doctorate) within the last five years. The SAS-ECIG is a diverse committee that is dedicated to providing members with a unique experience to help promote and succeed in their career. Together, we aim to support the professional development of early career scientists through award schemes, travel grants, as well as opportunities in leadership, outreach, networking, mentorship, volunteering, formal certification, and employment.

SAS Early Career Interest Group – Travel Awards

The Early Career Interest Group (ECIG) is happy to announce this year’s winners of Early Career Travel Awards: Dr. Olga Eremina and Dr. Malama Chisanga.

Olga obtained her Ph.D. in Analytical Chemistry from Lomonosov Moscow State University.  She is currently a postdoctoral fellow at the University of Southern California in Dr. Cristina Zavaleta’s research lab, where she utilizes SERS-based sensors for monitoring human and environmental health.  At SciX 2022, she will be giving the presentation “Breaking Multiplexity Limits of SERS Imaging to Enable Highly Specific Molecular Imaging and Spatial Profiling of Diseased Tissues”.  In this talk, she will describe her work with multiplexed Raman imaging to distinguish 26 different SERS nanoparticles with subcellular resolution.

Malama received his Ph.D. in Analytical Chemistry from the University of Manchester.  Currently, he is working in Dr. Jean-Francois Masson’s group at the University of Montreal as a postdoctoral fellow.  In his research, Malama is using SERS sensors and chemometrics for medical and clinical applications.  Malama’s presentation at SciX 2022 is titled “SERS on a chip: Multiplexed detection of cross-reactivity of SARS-CoV-2-specific antibodies in clinical samples”.  His talk will focus on multiplexed detection of antibody cross-reactivity using SERS-active tags that are immobilized on a chip within a microfluidic cell.



These awards, in the amount of $750 each, will be used to assist the awardees with travel expenses related to attending SciX 2022.  The Early Career Interest Group would also like to thank all of the other applicants for taking the time to apply for this year’s award.  It was an honor to learn about each of you and the exciting research you are conducting.

Abstract Title: High-throughput Raman flow cytometry for directed evolution

Abstract: Flow cytometry is an essential tool for single-cell analysis. Fluorescence-flow cytometry allows analyzing thousands of single cells based on their fluorescence signal using fluorescent staining. However, the need for fluorescent labels is problematic due to its low specificity for small biomolecules, cytotoxicity of staining protocols, and autofluorescence interference. Raman spectroscopy obtains a biochemical fingerprint of single cells in a label-free, non-destructive manner. However, its small cross-section results in slow signal acquisition and low throughput, hindering the interrogation of large cell populations. Coherent Raman scattering methods such as coherent anti-Stokes Raman Scattering (CARS) enhance the light-matter interaction, enabling faster acquisitions and allowing high-throughput implementation. We use Fourier-transform CARS (FT-CARS) to obtain a Raman spectrum every 42 µs in the fingerprint region and analyze cells based on their vibrational characteristics. Integration of a rapid-scan FT-CARS spectrometer and a microfluidic device with acoustic focusing enables Raman flow cytometry at 200 cells/s. With this method, we demonstrated high-throughput flow cytometry of various microalgae such as Chromochloris zofingiensisEuglena gracilis, and Haematococcus lacustris based on their intracellular contents of carbohydrates, proteins, chlorophyll, and carotenoids. We also show that our FT-CARS flow cytometer can characterize differences in metabolic activity among Euglena gracilis clones generated by ion beam mutagenesis. We believe that the combination of ion-beam mutagenesis and Raman flow cytometry opens a new path to metabolic engineering, that is, creating and characterizing cells with specific phenotypes in a label-free manner.

Brief Bio: Dr Julia Gala de Pablo studied a BSc in Physics and a BSc in Biochemistry at the University Complutense of Madrid (Spain). In 2015, she moved to the University of Leeds (UK), defending her PhD in Raman spectroscopy of live single colorectal cancer cells in 2019. She is currently a JSPS postdoctoral fellow at the University of Tokyo in Goda-lab working in Fourier-Transform Coherent anti-Stokes Raman Scattering for flow cytometry and sorting.

Abstract Title: Polarization sensitive photothermal mid-infrared spectroscopic imaging of human bone marrow tissue

Collagen quantity and integrity play a significant role in understanding diseases such as myelofibrosis (MF). Label-free mid-infrared spectroscopic imaging (MIRSI) has the potential to quantify collagen while minimizing the subjective variance observed with conventional histopathology. Polarization-sensitive Infrared (IR) spectroscopy provides chemical information while also estimating tissue dichroism. Quantitative chemical and structural information can potentially aid MF grading and improve pathological agreement on the diagnosis by quantifying chemical and structural information of collagen fibers. We are presenting the first study of polarization-dependent spectroscopic variations in collagen from human bone marrow samples. We translate polarization-sensitive IR studies in animal models into a clinically viable method for analyzing human clinical biopsies. We developed a new polarization-sensitive optical photothermal mid-infrared (O-PTIR) spectroscopic imaging scheme that enables sample and source independent polarization control. The proposed imaging scheme allows tissue imaging at higher spatial resolution (0.5µm) with reduced imaging time. OPTIR provides 0.5µm spatial resolution, enabling the identification of thin (≈1µm) collagen fibers that were not separable using Fourier Transform Infrared (FTIR) imaging in fingerprint spectral region at diffraction-limited resolution (≈5µm). We also propose quantitative metrics to identify fiber orientation from discrete band images (amide I and amide II) measured under three polarizations. In previous studies, for collagen fiber orientation, mid-IR imaging was collected using IR lights of multiple polarizations in the range of 00 – 1800. Imaging tissue with multiple polarizations is time-consuming, especially at high spatial resolution. Hence, we proposed a clinically viable imaging scheme to quantify collagen fiber orientation by imaging tissue at only two discrete bands and three polarizations (two orthonormal polarization and the third one at 450 from both orthogonal polarizations). The proposed imaging scheme provides sufficient information that can be translated into a quantitative metric using Jone's calculus. However, mid absorbance imaging with two orthogonal polarizations is inadequate for identifying collagen orientation in clinical samples since human bone biopsies contain collagen fibers oriented in multiple directions. Here, we address this challenge and demonstrate that three polarization measurements are necessary and sufficient to resolve orientation ambiguity in clinical bone marrow samples. Our study is also the first to demonstrate the ability to spectroscopically identify thin collagen fibers (≈1µm diameter) and quantify their orientations, critical for accurate grading of human bone marrow fibrosis.

Brief Bio: Rupali Mankar is a postdoctoral fellow at the University of Houston. She holds a Ph.D. from the University of Houston. Her research focuses on combining IR spectroscopy and machine learning to improvise spectroscopy for clinical translation. She was awarded a postdoctoral fellowship award by the National Laboratory of Medicine (NIH-NLM) for her Biomedical Informatics and Data Science field. In her Ph.D. work, she has automated osteosclerosis (one type of bone marrow fibrosis) and currently working on overcoming the diffraction-limited spatial resolution of IR imaging for comprehensive evaluation of bone marrow fibrosis.
