Research focus- 

For my senior design project, under the guidance of Dr. Sanjay Shah, my team researched and developed an innovative Biofilter/Heat Exchanger system. This system leveraged chicken compost as a filtration medium to purify air being expelled from an indoor hog farming operation. As the compost medium underwent biological reactions, it generated heat. We harnessed this by integrating a pipe system through the medium, which allowed the redirection of fresh air back into the hog facility, serving both as a purification and heating solution.  For this project we won the 2007 NCSU Undergraduate Research Symposium by Sigma Xi Scientific Research Society. 

Career path-

My career trajectory has been unconventional yet rewarding. It began with an internship in an electromechanical lab, conducting failure analysis while still in school. From there, I transitioned into roles in mechanical design engineering, software development and product management. Today, I’m an entrepreneur, owning a small business in the food manufacturing industry. Additionally, I’m passionate about community engagement and support other small businesses by organizing free community events in downtown Raleigh to foster community connections.  I also currently serve as an advisory board member for the BAE department and the City of Raleigh Environmental Advisory Board.

For current BAE students, my suggestion is to welcome new opportunities and maintain an open mind regarding future career directions. Over the course of your professional journey, you’ll come across numerous opportunities that may lead to unexpected paths. Take calculated risks, explore diverse prospects, and never hesitate to consider new ventures. Your ultimate destination may surprise you.

Life in BAE 

“My experience in BAE was truly fantastic across all aspects, with special highlights on technological innovation and teamwork. I was involved with the Alpha Epsilon association and ran some projects by initiative. However, due to the complexity of my research I was focused on it and  I actively sought entrepreneurial opportunities inside NCSU and outside, a venture that was both challenging and rewarding. This entrepreneurial spirit was fueled by the exploratory nature of my research, which demanded innovative thinking and diving deep into complex problems. 

Deciding what to do after completing my degree was a deeply introspective and transformative journey, significantly influenced by my master’s program and pivotal mentorship from Dr. Sanjay Shah, which offered support, cutting-edge tools, and challenging opportunities that propelled my immersion into deep conceptualization and research. This period of exploration, characterized by excitement and uncertainty, led me to leverage my skills in R, Python, Ansys, and SolidWorks, and to engage deeply in coursework on statistical analysis, precision agriculture, and AI applications for UAVs. My decision to pursue a career blending research, AI, and digital innovation, though complex, was clarified through hands-on experiences, mentor guidance, and coursework aligned with my aspirations.”

Career Path

“My career journey started in the construction and agricultural machinery sector in Peru, transitioning through roles of increasing importance from a Market Analyst at Ipesa Sac (John Deere Dealer in Peru) to various strategic positions at european corporate company  Atlas Copco and Epiroc, culminating as a Key Account Manager. Over two decades, this path laid a solid foundation in sales, leadership, management, and the technical nuances of heavy machinery across agriculture, construction, and mining. A pivotal shift occurred when I decided to advance my education with a Master of Science in Biological and Agricultural Engineering at NCSU, diving into the latest technologies and methodologies. This academic endeavor steered my career towards digital innovation, leading to my current role at Crumpler Pipe INC., where I spearhead digital transformation initiatives, blending my rich industry background with advanced technical expertise in product design, digital platform management, and AI-driven sales and marketing strategies working with big-data, for large scale markets and products.

As you navigate your journey in Biological and Agricultural Engineering, remember the journey is split into ‘before’ and ‘after’ phases, enriched by classroom learning and peer interactions. Embrace every opportunity to learn and grow, seeking guidance and feedback from mentors. This blend of academic knowledge and practical experience lays a strong foundation for your future career. Cherish the journey, and remain open to the myriad opportunities that come your way, as they will shape your professional path.”


Emine Fidan

Fidan graduated from the BAE Department with a PhD in 2022. Natalie Nelson was her advisor. Her research focused on “understanding flood and water quality dynamics during extreme storm events using machine learning and data analytics,” she says.

Life at NC State

“I loved my experience in BAE at NC State! I was heavily involved in the departmental Graduate Student Association and really connected with the researchers I met in the department. I will forever be grateful for my PhD experience at NC State because it introduced me to my life-long best friends, provided a healthy environment for me to learn and research, and prepared me well for a career in academia.”

Career Path
“My professional journey began with undergraduate research at the University of Tennessee, where we applied engineering and conducted fieldwork to study water quality and morphology in streams/rivers. This experience inspired a deep passion that warranted exploration. Seeking additional research exposure, I interned at Oak Ridge National Laboratory, where I immersed myself in the study of applied aquatic ecology and ecotoxicology. These experiences solidified my commitment to a research-intensive career path, while also highlighting the importance of diversifying my skill set beyond fieldwork. Consequently, I pursued studies in water resources engineering at NC State, focusing on analytical and computational approaches. This decision laid the groundwork for my current work, where I now leverage my field work experiences and my computational knowledge to understand water resources and ecological system dynamics during major storm events.
I knew upon completing my PhD degree that I wanted to continue conducting research, and since I loved teaching as well, I knew that a university position would be the most fulfilling for me. Ultimately, I have my heart set on being the type of professor that Dr. Nelson in NC State’s BAE is: one who values progress in research and teaching, and also one who knows when to celebrate the small achievements made along the way.”

Life in BAE

I can’t say enough positive things about BAE at NC State. It has changed my life in many ways and set me up to succeed professionally. It has allowed me to pursue a career that brings me a lot of fulfillment. The relationships I built at Weaver Labs will last a lifetime, and I look forward to seeing how I interact and collaborate with old classmates and professors in the future. It is such a welcoming place and the resources available to students are limitless if you seek support and mentorship. 

I was heavily involved with ASABE from my first semester at NC State and I credit a lot of the opportunities I had to that participation. I spent two years involved as a general member and decided to take a leap of faith and run for president my junior and senior year. Serving as president was a responsibility I took great pride in. With the help of an amazing officer team, we delivered so many quality guest speakers, coordinated industry tours, and hosted fundraising events. I also participated in the Graduate Student Association as Historian for a year, was a BAE Ambassador for 2 years during undergrad, and was a member of Alpha Epsilon for 2 years.


Career Path

I had a difficult time deciding on a career path to pursue, simply because there were so many options and routes available based on my skillset and experience. After having industry internships in the bioprocessing (Novozymes) and stormwater (WithersRavenel) sectors during my undergraduate degree, I felt I had not yet found my niche in Bio and Ag Engineering. That prompted my interest in sticking around for another two years to pursue a master’s degree in agricultural waste management. This gave me time to build my skillset and explore more career paths. I wanted a career and job that allowed me to get outside and work directly with people. For that reason, I heavily considered working with NC Cooperative Extension and the Natural Resource Conservation Service (an agency under the USDA). However, I was fortunate to find an opportunity to work in a similar area I studied for graduate school, agriculture waste management, as an Assistant Project Engineer at Agri-Waste Technology in Apex, NC. In this role I get to work directly with poultry and swine producers by providing recommendations on ways to improve their operations. I use my engineering knowledge to help them access USDA grants to make necessary improvements to their farms. I get to build personal relationships with people, and I feel like I am genuinely helping people in need while also caring for the environment and feeding the world responsibly.


The things that drew you into this department, the family environment, the care for the environment, the prospect of working hands-on in the field…those opportunities are out there. Just because you had an internship with one company that didn’t fit your desires does not mean other companies are all the same. You have worked hard and deserve a career that is fulfilling. With your knowledge and skillset you are valuable in the workforce and can absolutely find a company or organization that will fulfill your passions. Also, I highly recommend that you stay open minded as you progress through your degree program. I wouldn’t be where I am now if I hadn’t taken internships in such different areas, worked with professors on projects I knew nothing about at the start, or attended ASABE meetings for companies I thought I wasn’t interested in. Stay open to new opportunities and you never know what will speak to you and excite you, even if it wasn’t the plan you had in your head. It never hurts to meet people, learn new things, and grow as an engineer and an individual. Lastly, you have so much ahead of you to be excited about, but also slow down and appreciate the long days in Weaver because you will miss them someday!
