Constanza Paulina Silva Gallardo

Ph.D. Candidate at Biobehavioral Health

The Pennsylvania State University


English version:

Constanza Paulina Silva Gallardo is a Ph.D. Candidate in the department of Biobehavioral Health at The Pennsylvania State University. She is interested in the behavioral genomics of tobacco and alcohol use in mouse models and humans. Her past research has focused on the effects of nicotine exposure during adolescence and its effects on alcohol consumption and gene expression. She is currently studying the effects of reduced nicotine-content cigarettes (Spectrum) and their impact on genomic marks, craving, and withdrawal relief. She has experience as a laboratory technician and on genomic data analysis. Additionally, she has writing and communication skills in both Spanish and English.

Constanza Paulina Silva Gallardo es candidata a doctora en el departamento de Salud y Bio-comportamiento en la Universidad Estatal de Pennsylvania. Ella está interesada en las marcas genomicas y el comportamiento asociado al uso de tabaco y alcohol en modelos animales y humanos. Sus investigaciones anteriores han estado enfocadas en los efectos de la exposición a la nicotina durante la adolescencia y los efectos de éstas en el consumo de alcohol y expresión génica. Actualmente su trabajo de investigación se enfoca en los efectos de cigarros con contenidos reducidos de nicotina (Spectrum cigarettes) y su impacto en marcas genómicas, y alivio de sintomas de abstitencia. Constanza posee experiencia como técnico de laboratorio y en el análisis de datos genómicos. Además, posee capacidades de comunicación en inglés y español.

Fellowships and Training Grants

The Prevention and Methodology Training Program (PAMT; T32 DA017629)

The Prevention and Methodology Training Program (PAMT; T32 DA017629) has been funded by the National Institute on Drug Abuse (NIDA) since 2005. PAMT makes a unique contribution to the nation’s training of prevention scientists and to the NIDA portfolio by fostering careers that focus on integrating drug abuse/HIV prevention science and innovative methodology.

Biomedical Big Data to Knowledge Training Grant (B2D2K; T32 LM012415)

This NIH-sponsored Training Program comprises a diverse cohort of next-generation scientists engaged in integrative analyses of biomedical data to advance science and improve health. Students learn to develop novel algorithmic and statistical methods with which to build predictive, explanatory, and causal models for integrative analysis of electronic health records and genomics, behavioral, socio-economic, and environmental data to advance science and improve health. Trainees are supported for a period of two years as a part of their doctoral program.

BECAS CHILE- Chilean scholarship for international Ph.D. degrees (N° 72160326)

Competitive scholarship for Chilean students pursuing Ph.D. degrees abroad.
