Can you share one piece of career-related advice or wisdom with other early-career scientists?

One piece of advice I have for other early career scientists is to not be afraid of failure. Many things you try won’t work, but that’s ok. We learn more from failure than from getting something right on the first try. Don’t be discouraged but rather learn from those mistakes, keep working as hard as you can, and everything is going to be all right.

How do you feel about Biomaterials Science as a place to publish research on this topic?

Our publication in Biomaterials Science focuses on the development of an engineered biomaterials-based model to understand the immunomodulatory properties of lactate in vivo. The PLGA MP-loaded hydrogels recapitulate the immunosuppressive, “cold” tumor environment and serve as a proxy for the TME. As such, we can use this biomaterials construct to answer fundamental cancer biology questions in vivo, which dovetails closely with the scope of this journal.

I have often reviewed for the journal and found that the initial submissions sent on are of high quality. For me, the greatest strength of the journal is its editorial board and peer review policies.

What aspect of your work are you most excited about at the moment and what do you find most challenging about your research?

The work I am most excited the higher-risk projects in the group that keep us questioning.  I have a great team of researchers and it is their innovation, curiosity and unexpected results that gets me most excited. I feel that we are always close to the pulse of the developments of our field, more now than ever due to social media (twitter etc.) and online events. The most challenging aspect is maintaining momentum through funding support and maintaining continuity in skills within the group.

In your opinion, what are the most important questions to be asked/answered in this field of research?

I believe we need clever (not complicated!) solutions to advance healthcare and understand disease better. We need to learn from nature, but I also think we need to increase our awareness of nature and look to be more environmentally sustainable (and realistic) in our approaches.

Can you share one piece of career-related advice or wisdom with other early career scientists?

This will sound cliché but do keep trying and always keep your options open (don’t close any doors). There are plenty of people that want you to succeed so do listen to their advice. And choose your battles.

How do you feel about Biomaterials Science as a place to publish research on this topic?

I think it’s a great multidisciplinary journal. It has a broad scope, a strong profile thanks to a reputable publisher and association with a leading learned society and has a very accessible and friendly publication process. For my research, these qualities make Biomaterials Science most suitable to publishing high quality research that does not fit within the narrower scope of a nanotechnology or material science journal.

What aspect of your work are you most excited about at the moment and what do you find most challenging about your research?

I am very excited by the ability to control cell behaviour at single-cell level, through a combination of high-precision delivery and sensing. I can see how this can be used to build accurate models of tissues and organs. Our research is always quite challenging because we try something not attempted before, and that’s the interesting part about it. The less interesting challenges are the increase in administration and bureaucratic burdens that take the focus away from research.

In your opinion, what are the most important questions to be asked/answered in this field of research?

In exploring nanoneedles for delivery and sensing there are so many open, exciting questions that we are spoilt for choice. There are fundamental questions on how exactly these interfaces negotiate the cell membrane to grant intracellular access, and these are among the most interesting as they are quite unique to nanoneedles. There are more biological questions on the details of the biophysical interaction, and its implication for cell fate. And there are technological questions on how to design, manufacture and bring to market this exciting new technology.

Can you share one piece of career-related advice or wisdom with other early career scientists?

Do something that you like for as long as you like, and when you stop liking it, move on to something else. There are so many opportunities to be grabbed that it is not worth spending time being miserable.

Dr. Eliza Fong is an Assistant Professor in the Department of Biomedical Engineering at the National University of Singapore with joint appointment at the N.1 Institute for Health. Through her Translational Tumor Engineering (TTE) program, Dr. Fong hopes to change the way cancer patients are currently treated. Most cancer patients do not receive individualized drug treatment regimes. Rather, they receive ‘standard-of-care’ regimens where they are treated with drugs that are known to ‘work’ for a general cohort of patients with the same cancer type. Using biomaterials engineering strategies, Dr. Fong develops platforms to grow patient tumor tissues (organoids and explants) outside the body, so that these engineered tumor tissues can be used to better test drugs and identify the best drug regimen for individual patients. Dr. Fong also looks at recapitulating stromal heterogeneity in these engineered models to enable the discovery of potential new targets in the tumor microenvironment.
