Postdoctoral positions

Ingrid Alvial


Biologist graduated from Universidad de Concepción, MSc and Dr in Ecology and Evolutionary Biology (Universidad de Chile). During his master’s degree, Ingrid studied the top-down and bottom-up controls on the community structure of phytoplankton in the Chungará lake. In her doctorate thesis she studied the genetic and population structure in the cosmopolitan dragonfly, Pantala flavescens through mitochondrial and nuclear markers in continental and insular localities, in order to determine if a genetic differentiation patterns is reflected according increase in geographic distances, and specially in remote Pacific islands.

Currently, Ingrid is a postdoctoral research associate at the EME LAB, Universidad Católica del Maule headed by Dr. Hugo Benítez (supervise) in collaboration with the Ecology and Genetics Laboratory of Universidad de Chile, lead by Dr. David Véliz and the Entomology Institute of the UMCE, lead by Christian González.

Her research is focused on the morphological differentiation, genetic structure and presence of hybridization in the two biotypes of Culex pipiens (Cx pipiens pipiens and Cx pipiens molestus), along continental and insular localities in the national territory.

Margarita Correa


Agronomist from Pontificia Universidad Católica de Chile, MSc in Plant Protection and Doctor in Agricultural sciences (P. Universidad Católica de Chile). European Projects Engineer from the Université Côte d’Azur, Nice, France.

She studied Entomology at the Entomology laboratory of the National Agricultural Service (SAG), Chile. During her master thesis, Margarita studied the genetic and morphological characterization of cryptic mealybugs species (Hemiptera: Pseudococcidae), key pest species on Chilean vineyards. She performed her doctorate thesis in the “Biology of Introduced Populations” laboratory at the Institut de la Recherche Agronomique et Environnement (INRAE) at Sophia Antipolis, France. She specialized in molecular ecology and population genetics to study the diversity and invasion routes of pest species.

She had a post-doc at INRAE on the biological control of an insect pest in the insular context of Corsica, France. Finally, in 2019 she had a position at the ASTREDHOR institute, Paris, France, where she studied the biological control of insect pests on ornamental plants.

In 2017 she started collaborating with the Molecular Ecology laboratory of Universidad de Talca to study the impact of endosymbionts carried by aphids (Hemiptera: Aphididae) on their invasiveness and in 2021to study the impact of climate change on the bottom-up and top-down relationships on the plant-aphid-endosymbiont system.

Currently she is performing a Post-Doc with Dr. Benitez at EME lab, in collaboration with the Universidad de Tarapacá, to study the effect of climate change factors in the field and endosymbionts of aphids in morphometric characters associated with invasiveness. Also, she collaborates in current research projects and topics from the EME’s Lab.

Research Associate

Franco Cruz-Jofré

Veterinary, Doctor in Ecology and Evolutionary Biology at Universidad de Chile, currently hired at the Universidad Santo Tomas (Viña del Mar).

Dr. Cruz-Jofré has been working with the EME LAB as a research associate since the origin of the lab, currently with the Dr. Benítez they are working together in topics related to vertebrate morphometrics and ecology and evolutionary biology of Altiplano's Fauna.

Dr. Cruz-Jofré have knowledge in vetebrate morphology, and has been working also in Altplano's fishes from the genus Orestias principally to understand the origin and pattern of adaptation to these extreme environment.

Doctorate Students


Amado Villalobos

Biologists graduated from Universidad de Concepción.  His main area of work is devoted to evolutionary biology.  In his undergraduate thesis he performed an analysis integrating morphometric, ecologic and phylogenetic variables in the species sensulata of the native lizard Liolaemus pictus, in order to delimit species and propose conservation strategies.  For his master degree, at Universidad de Chile, he researched the association between digging character and performance phenotypes in a population of the native rodent Octodon degus, within a context of evolutionary ecology of behaviour.  Nowadays, in the Systematics and Biodiversity Doctorate Program, under the tutorship of Dr. Hugo Benítez, he intends to test phylogeographic and adaptive radiation hypotheses based on the wing variability of butterfly species from the genus Vanessa, using geometric morphometric tools.

Jordan Hernández

Biologist, currently doing his Doctoral Studies at the "Ecosystem Health" in Chile

at EME LAB and granted with the Scholarship from the Cape Horn International Center, where will be working with Invasive Species in Antarctica and SubAntartic environment focusing in flies (Trichocera maculipennis and Psychoda sp.)

His Master Thesis was in Colombia working with geometric morphometric on Fishes studying the patterns of Sexual Shape Dimorphism and their ecomorphology of  Caquetaia kraussi (Perciformes: Cichlidae)

Master Students

Pablo Lamilla


Environmental Biologist and student of the Master Program on Biological Sciences at Universidad de Chile. His main research area has been focused on understanding aspects related with zoology, ecology and evolutionary biology. During his undergraduate studies, Pablo worked in areas related with animal behaviour, by studying the exploratory conduct of an endemic rodent of Chile in new environments and his degree thesis dealt with a long-term research about asymmetry patterns in a context of sexual selection of the endemic bird to temperate forests in Chile and Argentina, Aphrastura spinicauda (thorn-tailed rayadito). Currently, he intends to contribute to the knowledge of the proximate and ultimate causes explaining the diverse morphological and adaptability patterns of organisms, trying to understand and prove the importance of studying intra-individual morphological variability and developmental stability as a valuable early indicator of health and quality of life of natural habitats and wild animals, as well as the contemporary factors of environmental stress to which they may be subject. For this purpose, his master work intends to study the effect of pollutants in fluvial systems on fluctuating asymmetry of catfish populations (Trichomicterus aerolatus), using morphometric tools of the biological shape. Pablo works on his graduate thesis in the Ecology and Genetics Laboratory of the Ecology and Biodiversity Institute (IEB) at Universidad de Chile, headed by Dr. David Véliz, the Laboratory of Ecology and Evolutionary Morphometrics at Universidad de Tarapacá, led by Dr. Hugo A. Benítez and the Limnoecology Laboratory at Universidad de Playa Ancha, headed by Dr. Claudio Quezada-Romegialli. 

Laboratory Technician


Rodrigo Órdenes-Claveria

Agronomic Engineer graduated from Universidad de Tarapacá.  During his undergraduate program, he studied the morphological adaptation of the non-indigenous species Bagrada hilaris in its invasive process over Chilean land.  Currently, he works in the laboratory of Dr. Benítez studying the morphometric variation processes in insects and currently is located in the city of Cochabamba in Bolivia doing studies in Graphic Design

Rocío Álvarez-Varas


Veterinary, MSc Natural Resources and Dr. Ecology and Evolutionary Biology (Universidad de Chile).  During his Master Degree, Rocío studied the morphological variation and phylogeographic patterns of six bird species from the genus Phrygilus. Her doctorate thesis was devoted to studying the morphological and genomic differentiation of Chelonia mydas (green turtle) in the Western Atlantic and Eastern Pacific, using geometric morphometric techniques and Next Generation Sequencing (NGS).

Among their research interests are the study of triatomines insects vectors of Chagas’s disease. I am currently studying the Doctorate Program in Biomedical Sciences at the Universidad San Francisco Xavier de Chuquisaca under the guidance of Dr. Hugo Benítez, investigating the morphological variability of populations of Triatoma infestans present in inter-Andean valleys and the Chaco of Chuquisaca, applying geometric morphometrics tools. During her PhD thesis currently three articles are published studying the morphological plasticity of T. infestans as mechanisms of biological adaptation, sexual dimorphism and Fluctuating Asymmetry.
