See the quiz, "Are you PLANT-wise?"
Undergraduate students are essential to the smooth functioning of the lab, and a number of them have become valued junior colleagues.  The relationship truly is symbiotic, and the opportunity to do research that may result in publication insures that the student stands out, whether beginning a job directly after a bachelor's degree or pursuing an advanced degree. It doesn't hurt to learn all the techniques either!

Christine working with the big data base
Christine Ackerman  from Slidell, Louisiana, majored in biology .  She  joined the lab as a junior and learned a variety of techniques to help with the yeast research.  She specialized in photography, using the digital system in the Socolosky Microscopy Facility to capture images of the yeasts from cultures.

Major: Biological Sciences

BS degree: Spring 2003
 


 LaToya and Ning Zhang
LaToya Barber from Las Vegas, Nevada, worked in the lab when she was a Junior Biology major from Xavier University of Louisiana. LaToya had plans to persue a Ph.D program in immunology or attend medical school. LaToya was at LSU as part of the LAMP program in the summer of 2001. In her first research experience LaToya worked with Ning Zhang on a project investigating the link between population genetics of Discula destructiva and its pathogenicity to dogwood trees. LaToya is helping Ning collect data on the extent of the infection cause by each different strain. As a newly elected MARC Scholar at Xavier University, in Fall 2001 LaToya began a research project with Dr. Mark Schleuter. We wish she'd stayed longer because she really worked hard! The last we heard was that LaToya had a choice of several medical schools that she could attend.

  • Population Genetics of Dogwood Anthracnose Fungus (Discula destructiva Redlin). MSA, Salt Lake City, Utah, August-September 2001 (with N. Zhang and M. Blackwell) Abstract:  Dogwood anthracnose caused by Discula destructiva affects several native dogwood species in North America (Cornus florida in the east and C. nuttallii in the west). Since the first reports of the disease in the 1970s, infections have spread to British Columbia and over twenty states in the U.S. The fungus was believed clonal; however, our studies using DNA fingerprinting by amplified fragment length polymorphisms (AFLPs), sequences of the internal transcribed spacer (ITS), and pathogenicity tests detected variation in the D. destructiva populations. Twenty genotypes were identified among 72 isolates from both western and eastern United States. Analysis using distance methods separated the western from the eastern isolates. Seventeen genotypes were detected among eastern isolates, but only three from the west, indicting that the eastern populations may be more diverse. Among 11 isolates collected in 1999 from an area of approximately ten square kilometers in Catoctin Mountain Park, Maryland, we found eight different genotypes. Compared to collections made at the same locality in 1990, the diversity has not changed significantly. Therefore, although a few clones have spread widely and are dominant in certain populations, the fungus has retained its overall variability.

Katie Brillhart
Katie, a biological sciences major from Lafayette, Louisiana, began woring in the lab as a sophmore paid by Chancellor's research support in the fall of 2002.  She helped to write the descriptions of 300 isolates of yeasts for our Internet data base.  Katie's plans include pharmacy school and working as a pharmacist in a hospital after that.

Christina Dang

Christina (2003-2004) worked in the lab helping with culture of the yeasts and molecular work. In the summer of 2004 she participated in a research program at Loyola in New Orleans.
She completed her BS in Spring 2007, and will begin medical school in the fall at University of Texas Southwestern Medical Center in Dallas, Texas.
Doan Dang
Doan worked on several projects in the lab (1999-2001), including discovering yeasts on the surface of and in the gut of beetles. She and Rebecca Sweany (see below) surveyed large numbers of cultures each day to evaluate their success. Doan went to pharmacy school at Xavier University in New Orleans in fall 2001. 


Cathy Dugas DeRobertis
Cathy was the first student worker ever in the mycology lab.  A botany major, she graduated with honors (1985, left) and went to graduate school at the University of California at Riverside (MS 1987). From there she went to work in industry.  One of the projects that she did at LSU was to map wood-decaying fungi on the trees of the LSU campus; she also determined the number of mating genes present in one of the species common on living live oaks in the oak grove (n=39 --only one repeat!).  One species she found in late autumn is a basidiomycete common on campus live oaks (Inonotus dryadeus).  In a flash photograph on the lab web site home page you can see a slug on the basidiocarp;  slugs come out only at night.  See the statement by Cathy at the top of this page.  Cathy was supported by a USDA Cooperative Agreement to isolate mycotoxigenic fungi from differet varieties of Zea mays grown around the world. Photograph at right, taken in 2002. Cathy is employed as a researcher in the Department of Plant Pathology at LSU.

 


John Dugas
John was the second student worker ever in the mycology lab after being recruited by his sister Cathy, who became jefe to him as he worked hard to perfect his Spanish.   Yes, the lab is good training for the many who go on to graduate school in any field. John obtained a PhD from Indiana University --but in Political Science. He has taught courses in International Relations and Latin American Politics in the Political Science Department at Kalamazoo College, Kalamazoo, Michigan since the fall of 1995. 

John wrote, "I'm glad I'm still remembered there, even if my most memorable moment in the department was breaking five 4 liter flasks simultaneaously!" 

Elizabeth Ellent

Elizabeth, a Biological Sciences major, graduated from Isidore Newman School in 2005.She worked  in the lab during the 2005-2006 academic year testing specific primers on a species of yeast specific to a particular beetle throughout the eastern USA. After graduation, Elizabeth hopes to attend medical school and study either psychiatry or dermatology.

Cennet Erbil
Cennet  began her education at LSU in the fall of 2001. She earned a Chancellor's Leadership Scholarship Award and is pursuing a major in Biological Science. She is interested in both vocal and instrumental (French horn and piano) music. Cennet became a part of the research team in the fall of 2002. She has learned all the lab techniques, and is helping to edit the yeast photomicrographs for our growing Internet database. She has completed her first year of medical school (Spring 2006).

He is undecided about whether to pursue medical or graduate studies. He was helpful in transfering cultures and performed PCR reactions.


Helen Peebles
Helen worked in the lab during the fall of 1999.  A Plant Biology major with several young children, Helen is completed her last year as an undergraduate and went on to graduate school in Landscape Architecture.  She helped Dr. Sung-Oui Suh in his study of endosymbiotic yeasts of beetles.
 
 
 
 
 
 

 


Paul Radford (d. 1985)
Paul is the only student who ever walked into the departmental office and asked to major in mycology as an undergraduate.  Since that major was not available to him, he chose botany and worked in the mycology lab.  Paul was a natural researcher and quickly learned the chromatography and spectroscopy techniques necessary for determination of glycine betaine in the fruiting bodies of fungi.  Paul's death was a great personal loss to those with whom he worked closely with him. His independent thinking, natural apptitude for research, and enthusiasm was lost to mycology.

  • [Abstract. The recalcitrance of many myxomycetes to axenic culture makes field-collected sporocarps a desirable source of material for any broad phylogenetic study. Concomitantly, this approach raises problems of DNA contamination from other organisms; myxomycete fruiting bodies are known to support a rich fungal flora. The primer pairs used in this study would be expected to discriminate fungal- and myxomycete- derived 18S rDNA products. SM101/NS4 clearly will amplify ribosomal sequences from both groups of organisms, while, concordant with its original purpose, NS17 appears to identify the ascomycete-derived fragments present in SM101/NS4 amplifications. This provides a useful differential screening method to identify putative myxomycete rDNA fragments; we are presently cloning such fragments to further elucidate their origin. This approach may allow the development of myxomycete-specific PCR primers. The data obtained in this study suggest the existence of size variation in myxomycete rDNAs. The unusually large PCR product obtained from Fuligo is consistent with the presence of a group I intron, as is known in other Physarales. However, we cannot presently rule out the possibility that the absence of this fragment in NS17/NS4 amplifications reflects a fungal insert at the NS17 priming site. Minor size variation and mutiple PCR products have been reported previously from amplifications of myxomycete DNA. Although the starting material for DNA extraction was not specified, these data too may reflect co-amplification of fungal DNA.]

David Rush
David David is a Biological Sciences major from Oakdale, who started at LSU in fall 2003.  He began working in the lab in June 2005 and worked for a year. After that he decided to concentrate on excelling on the MCAT and working on courses.  

Brandye Sawyer (see her statement about the benefits of undergraduate research above)
Before automated sequencers were available, there was Brandye, who produced the best sequencing gels in the lab.  She spent a lot of her research time studying the ascomycete genus, Pyxidiophora (shown above left on moose dung).  Now we hear that she gets incredibly long runs on the automated sequencer in the Department of Animal Science at LSU where she works.  In addition to a full time job and raising her children, Brandye also is enrolled in graduate school. Brandye was supported by an NSF-REU supplement while she was an undergraduate student.  B. S. in Botany (1992)

Richard Sisson was a Biological Sciences major from Calhoun, Louisiana, near Monroe in north-eastern Louisiana.  Supported by an LSU "Top 100 Scholarship" and chosen for the Chancellor's Future Leaders in Research program, he began his career at LSU in Fall 2001 as a Biological Sciences major. Alas, Richard decided over the winter vacation to become a theater major. It's a small state: Richard's parents have shopped at  Spat's Pharmacy in Monroe, Louisiana.  Spat's is the pharmacy established by Joey Spatafora's father. 

Major: Biological Sciences to Theater!


Stacey L. Soileau
Stacey helped to show that Discula destructiva, the causal agent of dogwood anthracnose, does not have different vegetative compatibility groups in North America.  Working with Ning Zhang, Stacey paired isolates from the eastern United States and the western United States among themselves and with each other to determine if a zone of interaction could be detected at the meeting of the different mycelia.  Stacey also isolated fungi from spiders in a summer project in collaboration with  Todd Bukowski and Terry Christensen. She was supported by an NSF-REU award and an LSU "Top 100 Scholarship."  Stacey was one of fifty students chosen to receive Chancellor's research support upon coming to LSU during her time in the lab (Fall 2000-Fall 2001).

Melissa Spera, a biology major from the New Orleans area, began work in the lab in  January 2005. She did not work for very long, but Melissa quickly learned many techniques and in her  short stay she helped us out a lot. On the side she served as 2005 Queen of Thoth and brought us close to the real New Orleans Mardi Gras! BS Spring 2005. Melissa attended graduate school in parmacology at Tulane University beginning in the fall of 2005. Despite delays because of Hurricane Katrina, she completed an MS degree in Fall 2006.



Ebony Spikes
began research in the lab in Spring 2000.  She produced a literature survey and analysis of species of Achlya, and she continued in the lab by working on yeasts from the gut of beetles that eat basidiocarp tissues.  Ebony provided data on carbon and nitrogen utilization patterns of these fungi, the topic of her honor's thesis. She was supported by NSF-REU supplements and the LSU "Top 100 Scholarship." In Summer 2001 she had support from LAMP. Ebony spent the summer of 2000 at the Harvard School of Public Health doing research that culminated in a local research presentation ("Development of a gene expression system in the protozoan parasite Giardia lamblia"). Ebony received special recognition at LSU when she was chosen outstanding junior in the Honors College and in addition won the Honor's College Sternberg Award. Ebony has been choosen as a Goldwater Scholar for 2001-2002 and Outstanding Junior at LSU.  Ebony attended Oxford University and the London School of Hygene on her British Marshall Scholarship and received a master's degree in Spring 2006. Next? --she plans to attend medical school.

Team work: Rebecca Sweany and Doan Dang (see above)
Rebecca Sweany  began a project in the lab working with Doan Dang to evaluate the potential of several different projects upon which they might continue research.  For example, they have looked for yeasts reported by a colleague in root nodules of clover. Thus far, in addition to lots of Rhizobium, they have discovered cyst knot nematodes in one clover population on the campus and an apparent fungal root parasite --but no yeasts. Currently, Rebecca is working on the beetle yeast project, and she surveys large numbers of cultures each day to evaluate their growth. Doan left us for pharmacy school in fall 2001. Rebecca returned after a summer of working as a volunteer at a nature center in New Orleans and a trip to Africa. Rebecca has been supported by NSF REU funding. Rebecca is employed as a researcher in the Department of Plant Pathology at LSU.

Amy Whittington
Amy came to the lab for the summer 2002 from Dr. Amy Grooters's lab in the vet school where she had worked in a study of oomycete parasites of dogs and other mammals.  We will take her back at any time.  One of  her jobs in our lab was to photograph over a hundred yeast isolates using a digital camera.  During this work she discovered ascospores in some of the passalid gut yeasts --the only sexual spores we had found in beetle gut yeats.  Amy did photography, PCR and sequencing reactions, culturing, and anything else that needed to be done. Amy entered medical school in Fall 2004 medical school.
