Microbiology meets Jurassic Park: introducing Emma Harding

Emma Harding is a UNSW Woman in Maths and Science Champion and a passionate paleovirologist. Her PhD research is a unique combination of virology and evolutionary biology, focussing on the distribution, evolution and function of endogenous viral elements in vertebrate genomes. With an interest in marsupials, she investigates the prevalence and expression of endogenous viral elements from RNA viruses in cells. 

Since a young age, Emma has always been fascinated by science, with a particular interest in animals and paleontology. The film Jurassic Park contributed to her attraction to science (and it certainly helped that there’s a Dr. Harding in the second film). Now she works as a paleovirologist, where she is interested in the interplay between viruses and their hosts as well as the impact of viruses on the evolution of animals. 

Emma started her tertiary education with a bioinformatics major at UNSW, using computational science to address biological questions. During her first year she completed microbiology courses, where she became interested in the complex arms race between viruses and their infected host. Eager to learn more, Emma decided to change to a major in Microbiology to better understand the complex processes between microbes and the immune system. 

She undertook her Honours year under Prof. Peter White in the School of Biotechnology and Biomolecular Sciences at UNSW, investigating broad-spectrum antivirals against positive sense RNA viruses. In this research, she focused on a mosquito-borne family of viruses termed Flaviviridae, which include Zika virus, Dengue virus and West Nile virus. Her project involved expressing a viral enzyme called RNA-dependent RNA polymerase (RdRp) in bacterial cells and screening them against an array of antiviral compounds, with the aim of identifying drugs that could inhibit Flaviviridae. Emma worked as a Research Assistant in the same lab to finalise her experiments and investigate PhD opportunities. 

Emma continued her postgraduate studies under Prof. White, commencing a PhD in 2020. Emma’s PhD research focuses on viral “fossils”. When a virus infects a host, DNA from the virus can enter the genome of the infected host and remain integrated through millions of years of evolution. These remnants of previous viral infections can be used as “fossils” to trace the evolution of viral families. Emma is interested in determining whether they have an evolutionary advantage, such as in normal viral defence or in developmental processes. She focuses on the viral families Bornaviridae and Filoviridae, which, despite the fact there are over 160 viral families, are among the most conserved viral fossils in vertebrates.  

Emma predominantly performs her research using bioinformatics, coming full circle from the early focuses of her tertiary education. She comments on this, saying that if you enjoy a particular subject, eventually you’ll find yourself in that field, even if it takes a few different paths to get there. Alongside her research, Emma is listed as a UNSW Sydney COVID-19 expert

Emma loves science not just as a career, but also as a hobby. She practices genetics in her spare time, using shrimp as her model organism of choice. She purchases different coloured dwarf Neocardinia shrimp, such as red shrimp and blue shrimp, and performs crosses, observing the colour of their offspring. She also enjoys playing Dungeons and Dragons, a fantasy game where players create their own characters that embark upon adventures together. Emma emphasises that, especially during the current pandemic, it is important to have hobbies and activities that keep you in contact with friends and family, whatever those hobbies may be.  

The more I talk to Emma, the more abundantly evident it is that science truly is her passion. One piece of advice Emma has for young scientists is to give everything a try. She recommends taking different courses at university until you find your niche.

Science, sustainability & salsa-dancing: meet Negin Sarmadi

By Allegra Angeloni

Negin Sarmadi is a PhD student at the UNSW Centre for Sustainable Materials Research and Technology (SMaRT@UNSW) specialising in waste management and recovery. Negin is one of the talented Women in Maths and Science Champions and is currently working on innovative environmental solutions to the world’s biggest waste challenges.

Negin completed her undergraduate and Masters degrees in mining engineering at the University of Tehran in her home country Iran. It was here she discovered just how essential waste management is to countless industries. She moved to Australia to commence her PhD at UNSW where she works on Green Steel, a green manufacturing project developed at SMaRT@UNSW. Her project focuses on utilising carbon and hydrogen from waste rubber tires, plastic and coffee grounds as an alternative to coke and coal in steel production.  

Sustainability is certainly topical, as more individuals and industries make a conscious effort to incorporate eco-friendly practices into everyday life. When I asked Negin to explain what exactly draws her to this research, she responded: “We lose a million tonnes of valuable material every year as a result of the weaknesses at mineral processing technologies at mines, so working on mine’s waste recycling and recovery section opened my eyes to the bigger world of waste deposits which was everywhere. If we continue as we have in the past few decades to produce waste with no outlook of recycling, we will face a severe problem in the near future.  

“This is only one side of waste management’s coin; the other side is money. This is one of the most profitable fields that only needs attention and nobility. If you do not care about the earth and the environment, at least you can care about making money. To be honest, both sides are essential to me.” 

Outside her work in waste management, Negin loves to cook. In fact, she is well-known for the delicious homemade cakes she bakes. She describes cooking dinner after a long day at uni as “meditation” and “me-time”. She also enjoys salsa-dancing, which helps her de-stress following a jam-packed day at work. 

I ended the interview asking Negin if she could share some inspiring words of advice for young women interested in pursuing a career in STEM. Her response did not disappoint: “Self-confidence is attractive as hell, and it comes from independence, knowledge, and hard work. No matter what your field is, the only important thing is choosing your area of interest and putting the courage to pursue your goals. Be focused, be determined, and be empowered; there is no limit to what we, as scientist women, can accomplish.”
