Phospholipid Division Award Winner Feature: Mitchell Culler

Q&A with Mitchell Culler, winner of the Phospholipid Division Award Winner

Bio: Mitchell Culler is a Ph.D. candidate in food science studying methods for preventing lipid oxidation advised by Dr. Eric Decker at UMass, Amherst.  His research involves the modification of lecithin to act synergistically with tocopherol for increased antioxidant activity in emulsion systems.  His master's degree research was advised by Dr. Federico Harte at Penn State University and involved the prototyping and development of an automated device to study the effects of emulsifying salts and environmental conditions on casein micelle structure.  Mitchell holds a BS with honors in food science and a BA in English as well as minors in nutrition and agribusiness management from Penn State.  Additionally, he has research experience as a visiting scholar at the Universitat Autònoma de Barcelona (UAB) in Bellaterra, Spain where he developed an automated system to use light backscattering to measure coagulation time in cheesemaking, advised by Dr. Manuel Gahete.  Mitchell also gained research experience at the University of Cordoba in Cordoba, Spain working on a project advised by Dr. Raul Luque examining a link between a high-fat diet and somatostatin/cortostatin expression in mouse breast tissue.

1) What was your reaction when you learned you won Phospholipid Division Award?

I am absolutely thrilled to win this award, and I am very excited about what it represents.  As anyone who has spent any time doing research can attest, there are a lot of late nights in the lab and failed experiments that leave you empty handed with respect to data.  It feels really great to be recognized for all the hard work that goes into my research, and I feel honored to have been able to make a contribution that furthers scientific knowledge.

2) How did you get started in the field that you are studying?

I originally found food science because I became interested in the ingredients in the food I was eating.  What has captivated my interest is how much my perspective has changed the more I have learned about the field.  In short, it has remained interesting to me.  Studying food science has allowed me to work on many different projects and in different areas of research.  From designing, programming and testing automated prototypes to extracting and using enzymes to modify phospholipids, I have gotten to have some pretty incredible experiences so far.

3) What challenges have you overcome during your course of study?

In the last year, the coronavirus pandemic has caused increased challenges while trying to do research.  In addition to restricting the number of people in the lab at once, it has added significant restrictions to our ability to work in the lab.  While I am not sure anyone is able to say they have fully overcome this obstacle yet, I have found that planning experiments in advance and being more intentional with how I am spending my time has certainly been a step in the right direction.

4) Do you have any words of wisdom for other AOCS student members?

Setting realistic expectations for what you are able to accomplish in a given time period is a really critical skill to start developing, particularly early on.  One of the biggest things I continue to struggle with is accurately estimating how long certain tasks will take me to complete.  When you are planning out experiments, it is definitely important to take Murphy’s law into account and leave some extra time in your plan to get things finished.

5) How has winning the AOCS Phospholipid Division Award helped you develop as a young scientist?

Winning this award has given me a platform to showcase my research.  Personally, it is been really affirming to have this recognition from AOCS, particularly in my research area of phospholipids.  It can be easy to be overly critical of yourself when working in research because progress is often slow, so it can feel like you are not really getting anywhere.  Receiving an award like this is a great opportunity and reminder to look back at the work you have done and recognize how far you have come.

6) Can you tell us about your current research?

My Ph.D. research is on the topic of creating a modified lecithin using phospholipase D from various plant sources to transphosphorylate the lecithin head groups so that they can increase the efficacy of tocopherol as an antioxidant in food emulsion systems.  Typically, phosphatidylcholine (PC) has been shown to be a pro-oxidant in emulsions; however, phosphatidylserine (PS) and phosphatidylethanolamine (PE) are able to recharge alpha-tocopherol-quinone back to its active form.  Therefore, creating a high PE or PS lecithin from natural sources will extend the effectiveness of tocopherol, thus increasing the shelf-life of these emulsion-based products without the need for synthetic antioxidants.

Two minutes with: Florencia De Alzaa

We love showcasing not only the valuable work of AAOCS members but also the personal side of our members. In this newsletter, we provide two minutes with Florencia De Alzaa, R&D Technical Engineer for Boundary Bend Ltd.

Florencia came to Australia and joined the Boundary Bend team in September 2016 where she is working as a R&D Technical Engineer. She finished her degree in Chemical Engineering in 2015 at Universidad Nacional de Cordoba, Argentina. After graduation, Florencia has completed several Postgraduate Diplomas in Australia, including ‘Leadership and Management’, ‘Project Management’ and ‘Innovation and Design Thinking’. Florencia is an Associate Member of the Institution of Chemical Engineers (AMIChemE) and a Member of the Institution of Engineers Australia (MIEAust). Her recent research in the food industry has included: ‘Chemical and physical changes to fried chicken’, ‘Chemical and physical changes in oils during heating’, ‘Study of cooking oils suitability for Teflon coated cookware’, ‘Preliminary results of Evaluation of Chemical and Nutritional Changes in Chips, Chicken Nuggets and Broccoli after Deep Frying with Extra Virgin Olive Oil, Canola and Grapeseed Oils’.

Every day at work… I am faced with new challenges. It is hard to define a typical day in my line of work. Sometimes I am researching, reading and writing about various topics. Recent research in the food industry has included: chemical and physical changes to fried chicken, chemical and physical changes in oils during heating. Other days I find myself in meetings, working with contractors, suppliers and with internal cross-functional teams to run R&D projects.

My favorite part of my job is… that it never gets boring! I have the opportunity to work with colleagues from different backgrounds and work towards solving problems and develop solutions that can be challenging but rewarding. 

Away from work, I like to… do yoga or a stretch session. I really enjoy playing with my creativity and I often draw, paint, and take artistic photographs. I also practice aerial silks, and, because I recently moved close to the beach, I am learning to surf.

If I could meet anyone, it would be… the authors of the book Frying Technology and Practices (Kathleen Warner). I referred to this book as a bible when researching cooking oils in Australia. I found the theoretical discussions on oil chemistry, oil degradation mechanisms, and the practical aspects related to frying including regulatory matters well described. 

When listening to the radio I listen to… Spotify radios and podcasts. I am passionate about the olive tree, all its related products and its health benefits, if I would have to recommend a podcast it would be “The Olive Wellness Institute” podcast. They always interview experts in this industry sharing the science behind it. 

Congratulations to AAOCS member [soon to be Dr.] Leonie Walter

AAOCS student member, Leonie Walter, submitted her Ph.D. thesis entitled “Understanding small and large milk fat globule phenotype variation in dairy cows through milk lipidomic characterisation” in August 2019 and graduated earlier this year. Her Ph.D. was conducted through the Faculty of Veterinary and Agricultural Science at the University of Melbourne in conjunction with CSIRO, under the supervision of Professor Brian Leury, Dr. Richard Fry and Dr. Amy Logan.

Milk fat globules (MFGs) are spherical structures comprising a neutral lipid core that is surrounded by a three-layer membrane. Individual variation in MFG size is observed within dairy herds and, if selected for thorough breeding programs, could be exploited for a more targeted milk production for specific technological streams. 

Her thesis’s initial experiment aimed to determine how much the average MFG size is affected by on-farm and animal-related factors within a herd subjected to the same diet and environmental conditions: Walter, Leonie, Sue Finch, Brendan Cullen, Richard Fry, Amy Logan and Brian J. Leury. "The effect of physiological state, milk production traits and environmental conditions on milk fat globule size in cow's milk." Journal of Dairy Research 86, no. 4 (2019): 454-460.

Based on the data collected for the first experimental chapter, cows were selected for the second and third experiment, which aimed to characterise the small and large MFG phenotypes through an in-depth lipidomics analysis. This analysis included the characterisation of the fatty acid profile of the MFG core by gas chromatography and the identification of the whole milk lipidome through targeted liquid chromatography-tandem mass spectrometry: Walter, L., P. Shrestha, R. Fry, B. J. Leury, and A. Logan. "Lipid metabolic differences in cows producing small or large milk fat globules: Fatty acid origin and degree of saturation." Journal of Dairy Science 103, no. 2 (2020): 1920-1930.

The third experiment, conducted in conjunction with Metabolomics Australia, presents the most extensive milk lipidomic analysis in the literature to date, with 301 detected lipid species. The results also revealed, for the first time, a potential role for ether phosphatidylethanolamine in the regulation of MFG size, showing a higher relative abundance of ether phosphatidylethanolamine in the milk from cows that tended to produce larger MFGs: Walter, Leonie, Vinod K. Narayana, Richard Fry, Amy Logan, Dedreia Tull and Brian Leury. "Milk fat globule size development in the mammary epithelial cell: a potential role for ether phosphatidylethanolamine." Scientific Reports 10, no. 1 (2020): 1-13.

The final experiment developed an in vitro model using cells purified from raw milk and grown on permeable membrane supports: Walter, Leonie, Richard Fry, Amy Logan and Brian J. Leury. "Investigation on the suitability of milk-derived primary bovine mammary epithelial cells grown on permeable membrane supports as an in vitro model for lactation." In Vitro Cellular & Developmental Biology. Animal (2020).

“Leonie, it has been an absolute pleasure to co-supervise your Ph.D., where I was able to watch you develop into a truly gifted and exemplary scientist. A huge congratulations for all that you have achieved, and I wish you all the very best for this next phase of your career”  Dr. Amy Logan (AAOCS member and outgoing Treasurer for the AAOCS).

And from all of us here at AAOCS, congratulations, Leonie! 

Other Ph.D. students who are graduating, we would love to hear from you or your supervisors to help you celebrate! Contact your Division of the AOCS Communication Specialist, Katrina Gaffney.
