Biography

Komal Singh is an assistant professor with a joint appointment at Mayo Clinic. Her research interest focus is to improve cancer treatment-related outcomes. Singh evaluates phenotypic and molecular risk factors for symptom occurrence and severity to determine underlying mechanisms using omics based methodologies. Understanding the underlying biological mechanisms associated with patient symptom experience may yield targeted interventions to alleviate adverse events after chemotherapy. Currently, she's investigating associations between chemotherapy-induced nausea and disruption in the gut microbiome composition profiles.

Research Activity

FUNDED RESEARCH (INTERNAL)

Tenure Track Assistant Professor at Arizona State University (ASU) and Principal Investigator. A Pilot Study of the Associations Between Chemotherapy-Induced Nausea in Breast Cancer Patients and Gut Microbiome Composition Profiles. Funded by Institute for Social Sciences Research (ISSR) from 05/15/20 - 05/15/20 Total ASU budget: $8000/year. This research project built on my post-doctoral and pre-doctoral work. This study will: evaluate feasibility of patient recruitment and retention, as well as specimen collection; and estimate the effect size for changes in gut microbiome composition profiles from T1 to T2 that are associated with the occurrence of CIN.

FUNDED RESEARCH (EXTERNAL)

Post-doctoral Fellow. Evaluate Phenotypic and Molecular Predictors of Chemotherapy-Induced Nausea. Funded by T32 NR016920 (NIH/NINR) Weiss/Miaskowski (multiple PIs) from 09/01/18-08/31/19. Total UCSF budget: Tuition + $51,000/year. My postdoctoral research project built on my pre-doctoral work. This study evaluated: additional molecular mechanisms associated with chemotherapy-induced nausea, and phenotypic risk factors associated with trajectories of chemotherapy-induced nausea over two cycles of chemotherapy. As a member of Dr. Miaskowski’s research team, I recruited and assessed breast cancer patients to investigate molecular and phenotypic risk factors associated with developing lymphedema after treatment.

Doctoral student. Evaluate Molecular Predictors of Chemotherapy-Induced Nausea. Funded by T32 NR016920 (NIH/NINR) Weiss/Miaskowski (multiple PIs) from 09/01/17-08/31/18. Total UCSF budget: Tuition + $24,000/year. This part of my doctoral research study evaluated the differentially expressed genes and perturbed biological pathways between patients who did and did not experience chemotherapy-induced nausea and determine molecular mechanisms associated with chemotherapy-induced nausea. In addition, as a member of Dr. Miaskowski’s research team, I recruited and assessed breast cancer patients to investigate molecular and phenotypic risk factors associated with developing lymphedema after treatment.

Doctoral student. Evaluate Molecular Predictors of Chemotherapy-Induced Nausea. Funded by T32 NR007088 (NIH/NINR) Weiss/Miaskowski (multiple PIs) from 04/01/15-05/31/16. Total UCSF budget: Tuition + $24,000/year. This initial step of my doctoral research study analyzed data for differentially expressed genes between patients who did and did not experience chemotherapy-induced nausea using gene expression methodologies (i.e., RNA-Sequencing and microarrays using patient blood samples) with a goal to determine molecular mechanisms associated with chemotherapy-induced nausea.

Doctoral student and Principal Investigator. Evaluate Phenotypic Risk Factors for Chemotherapy-Induced Nausea. Funded by American Cancer Society

(Grant number DSCN-15-095-01-SCN) from 09/01/15-08/31/17. Total UCSF budget: $30,000. This part of my doctoral research study evaluated for differences in demographic and clinical characteristics, symptom severity, perceived stress and QOL outcomes between patients who did and did not report chemotherapy-induced nausea in the week prior to their next dose of chemotherapy. In addition, demographic, clinical, symptom and stress characteristics were evaluated as risk factors for nausea group membership.

Doctoral student. Travel award. Funded by K-award (Grant number CA168960) Dr. Christine Miaskowski (PI) from 09/ 2014 – 05/2018. Total UCSF budget: $20,000. Funds were used for poster and podium presentation at national and international conferences.  

Doctoral student and Principal Investigator. Evaluate Phenotypic Risk Factors for Chemotherapy-Induced Nausea. Funded by El Camino Hospital Auxiliary Doctoral Scholarship from 09/2015 – 09/2017. Total UCSF budget: $3,500. This funding supported my training in statistics for doctoral research.

Graduate Student and Principal Investigator. Characterize Function of Cold Shock Proteins in Drosophila. Funded by NIH Graduate Research Fellowship from 09/1993 – 09/1995.
