Tellez’s areas of interest are empirical corporate finance, financial intermediation, and household finance. Her research agenda on financial intermediation uses rich micro datasets to explore how compensation incentives, loan officers’ limited attention, and lack of human capital impact bank monitoring and their effects on moral hazard outcomes.
Her current projects on household finance link consumer credit bureau data to household demographics and consumption choices to show how consumption patterns change in times of financial distress.
Tellez has presented her research at national and international conferences, such as SFS Cavalcade North American, European Finance Association (EFA), and Financial Management Association (FMA).
Outside of academia, Tellez has worked in commercial and investment banking in Latin America, where her primary responsibilities included investment portfolio and liquidity management.
