Current Graduate Students

Picture
Yuley Encarnación Piñeyro, Ph.D. Student (Fall 2019)

of Melocactus, M. praerupticola (Cactaceae) for her bachelor's degree at
the Universidad Autónoma de Santo Domingo. Yuley started at UF in the Fall 2019

Thomas worked on revisionary systematics of the Clematis subgenus Viorna (Ranunculaceae) for his M.Sc. He started in Fall 2020 and will be investigating species limits, polyploidy, biogeography, and phylogenetics of the Neotropical clade of Smilax for his Ph.D. 
Picture
Malu Ore Rengifo, Ph.D. Student (Fall 2021)

Picture
Esteban Jiménez, Ph.D. Student (Fall 2022)
Esteban has worked broadly on the Costa Rican (and Mesomaerican) flora, including broad scale floristics studies, and has also produced a treatment for the genus Aristolochia for Costa Rica during his M.Sc. and the University of Costa Rica.  Esteban will be working on the systematics of the genus Peperomia (Piperaceae) for his Ph.D. studies. 

Undergraduate Researchers

Picture
Natalie Heaton is an undergraduate researcher from the Department of Biology and has been working in the lab with Thomas Murphy on Smilax systematics. She is also a University Scholars Fellowship Program recipient. 

Research Scholars

Picture
Dr. Matias Kohler, Universidade Federal do Rio Grande do Sul (UFRGS)
Matias was a short term scholar working in the lab on the phylogenetics and systematics of the southern South American
Opuntia clade. His work has been greatly clarifying relationships and species limits among the South American prickly pears,
and he'll be addressing biogeographic patterns and morphological evolution as it relates to the entire Opuntia clade.
​He recently published the first Opuntia plastome.

Serena I. Achá Macias, Ph.D.
Ph.D. (Biology), University of Missouri, St. Louis, 2019
M.Sc. (Biology), Universidad Mayor de San Andrés, La Paz, Bolivia, 2013
Serena worked on the population genetics and species delimitation of Passiflora for her Ph.D. studies. She worked on ​phylogenomics of Cactaceae and capture-seq locus design for her post doctoral work in the Majure Lab, which was recently published.

Andre A. Naranjo, Ph.D.
Ph.D. (Botany), University of Florida, 2020
B.S. (Biology), University of Miami, Coral Gables, FL, 2015
Andre worked on the phylogenetics, biogeography, endemism, and ecological niches of the Scrub Mint Clade for his Ph.D. studies. He worked on spatial ​phylogenetics, functional trait diversity, and patterns of endemism in the Massif de la Selle/Sierra de Baohruco on Hispaniola for his post doctoral work in the Majure Lab. 
Picture
Bethany Zumwalde, Ph.D. Student, UF 
​Bethany will be tackling the cytogeography of
the multi-ploidal Cylindropuntia leptocaulis
​
(Cactaceae) for her Ph.D. 

Picture
Kelly Ho, Undergraduate Researcher (Graduated Spring 2022)
Kelly was an undergraduate researcher in the lab from the Department of Biology and worked on several projects, including bryophyte DNA barcoding and two new species descriptions and illustrations in Cactaceae and Melastomataceae. 

Picture
Raquel García Aponte, Undergraduate Researcher (Graduated Spring 2022)
Raquel was an undergraduate student in the Department of Biology and worked with Bethany Zumwalde on the cytogeographic analysis and characterization of ploidy across populations of Cylindropuntia leptocaulis, including carrying out fieldwork in the southwestern United States. She was awarded a University Scholars Program Fellowship for her work with Bethany on C. leptocaulis.

Picture
Allison Blankenship, Undergraduate Researcher (Graduated Spring 2021)
​Allison started in the lab in spring 2019 and worked on a number of projects in the lab, including plastid genome annotation in Simaroubaceae and DNA extractions for genome sequencing projects. She worked on the evolutionary and biogeographic history of a phenomenal group of Neotropical Simaroubaceae,
​the genus Castela, which we published in summer 2021. She was awarded the University Scholars Program Fellowship for her work with Castela. 

Picture
Ayress Grinage, M.Sc. Student (Fall 2019-May 2020)
Ayress worked on the systematics of the genus Sabal in the southern United States with a specific focus on the Sabal minor complex for her masters project.  She also worked on our campus flora project to enumerate the biodiversity found in our campus natural areas, including vascular and non-vascular plants and macrofungi, as well as other lab projects, including phylogenetics of Castela (Simaroubaceae); published in summer 2021. Ayress was a Bioscience Scholar in the Dept. of Biology at UF. She finished her M.Sc. in spring semester 2020. Ayress is now a Ph.D. student at Cornell University where she is continuing her work on Arecaceae!! We wish her well and know she is bound for great things!!

Dr. Peter Breslin worked in the lab at DBG, where he focused 
on the biogeography, phylogenetics and population demographics
of ​hummingbird-pollinated species of Mammillaria (Cactaceae)
in Baja, California, and a large phylogenomic analysis of the Mammiloid clade.
​See part of his work recently published in Taxon.

  Dawn O'Brien was a volunteer in the lab at DBG
  from 2014-1015 and helped  advance a number of
  important projects, including much of the whole plastome
​  sequencing in Opuntia. She is now working on her medical
  degree at the University of Arizona.

REMEMBERING

Picture
​ W. Mark Whitten
Ph.D. (Botany), University of Florida, 1985
M.S. (Botany), University of Tennessee, Knoxville, 1979
B.S. (Biology), Thomas More College, 1976
​
Mark was a man of many talents and the backbone of the herbarium
molecular laboratory. Although he was a specialist in the systematics
of Orchidaceae, he also worked on floristics projects, community
phylogenetics and much, much more.
We lost Dr. Whitten 
suddenly in mid-April 2019. He will never be
​far from our hearts, and we will forever miss him.
