Current students

I am looking for students (one undergraduated, one graduate) interested in combining field, laboratory and/or museum work to resolve questions about signal divergence, speciation and/or systematics of birds. The Department of Biology at Univalle offers master's and doctoral programs in Sciences-Biology. If you are interested in joining my lab, please, contact me.

Past students

Graduate students

Jessica Nathalia Sánchez. M.Sc. Biological Sciences (2023)

Jessica studied geographic variarion in song and morphology in the Black-striped Sparrow (Arremonops conirostris)​​ along the environmental gradient of the Upper Magdalena River Valley in Colombia. She was co-advised with Sergio Losada at Universidad del Tolima. Jessica worked as an environmental consultant before beginning a permanent position as a high school teacher in Tolima. 

Undergraduate students

María Paula Rodríguez. B.Sc. Biology (2022)

​María Paula combined different methods in integrative taxonomy to study geographic variation in genetics and phenotype, and determine species limits in the Chlorospingus flavopectus complex from South America. She was coadvised with Carlos Daniel Cadena at Universidad de los Andes. Then, she went on to the MSc program at University of Wyoming. 

Daniel Alejandro Gutiérrez. B.Sc. Biology (2021)

Daniel conducted playback experiments to test if territorial males of the Grey-browed Brushfinch (Arremon assimilis) exhibit seasonal variarion in behavioral responses to neighbors and strangers (Publication). He was coadvised with Carlos Daniel Cadena at Universidad de los Andes. Then, he went on to the PhD program at Florida State University. 


Fabian Leonardo Perea. B.Sc. Biology (2021)

Fabian monitored an urban population of the Bicolored Wren (Campylorhynchhus griseus) to test the effect of several variables of habitat, traffic and group size on home-range size variation. He was coadvised with José Gregorio Moreno Patiño at Universidad Industrial de Santander.  

Juliana Rodríguez-Fuentes. B.Sc. Biology (2019)

Juliana characterized the vocal repertoire of a population of the Grey-browed Brushfinch (Arremon assimilis). She also described diel vocal variation and repertoire-use sharing between neighbor males (Publication). Juliana was coadvised with Carlos Daniel Cadena at Universidad de los Andes. Then, she went on to the MSc program at the University of Groningen and Ludwig-Maximilians-Universität München. 

Santiago Ávila-Quintero. B.Sc. Biology (2018)

Santiago studied phylogenetic relationships among Diglossa flowerpiercers and the association between melanic coloration and variation in the MC1R gene in this genus. Santiago's thesis was supported by a Colombia Biodiversa grant. He was coadvised with Carlos Daniel Cadena at Universidad de los Andes. Santiago is currently pursuing a Master's degree at Lund University. 

María Isabel Castaño. B.Sc. Biology (2017)

​María Isabel conducted field work to estimate home-ranges of territorial pairs of the Grey-browed Brushfinch (Arremon assimilis), and determine whether home-range size was correlated with the physical condition of males (Publication1). She also characterized the breeding biology of this species (Publication2). María was coadvised with Carlos Daniel Cadena at Universidad de los Andes. Then, she went on to the PhD program at University of Rochester. 

Jessica Díaz-Cárdenas. B.Sc. Biology (2016)

Jessica studied the phylogeography of populations of the Plain-brown Woodcreeper (Dendrocincla fuliginosa) from the Orinoco and Amazon regions of Colombia. After completing bachelor studies at Universidad de los Llanos, she has worked as an environmental consulting for several ONG's and the Instituto Alexander von Humboldt. 

Katherine González. B.Sc. Biology (2016)

Katherine studied the phylogeographic structure of Colombian populations of the Straight-billed Woodcreeper (Dendroplex picus) as part of her bachelor studies at Universidad de los Llanos. She has worked as museum assistant and teaching lectures at Unillanos, while pursuing a Master's degree at Universitat Oberta de Catalunya. 

Nattaly Tejeiro-Mahecha. B.Sc. Biology (2016)

Nattaly conducted field, museum and laboratory work to determine phylogeographic affinities of populations of the Burnished-buff Tanager (Stilpnia cayana) from the Orinoco region of Colombia. After completing bachelor studies at Universidad de los Llanos, she has worked as an environmental consultant for several ONG's and the Instituto Alexander von Humboldt.
