COMMENCEMEN
WEEK!
INTERIM
HEAD’S NOTE
Good
morning. This is the Monday morning right after the commencement. Finally, we all can get a breather. As we pass the commencement week, I plan to skip a couple of weekly roundtables. I will still do 5/27, 6/10, and 6/24. For your information, I have started
to have weekly meetings with Dr. Kevin Otto about the transition.
Many
of us got a bit sentimental over the last weekend. I did as I attended last Thursday’s Graduate Dinner, last Saturday morning’s Graduate Celebration, and last Saturday afternoon’s Commencement Section 5. Graduation is a time for reflection. On last Thursday
evening, I asked a large crowd of graduating BME students, what kind of Purdue alum they would like to become. When thinking about this question, they could all get some help from distinguished alumni like Matthew Waninger, three-time Purdue alum and currently
Managing Director, Crossroads Pediatric Device Consortium. Matt gave an inspiring speech. Many thanks to Matt. It was so good to chat with the parents and loved ones of our graduating students on Saturday morning. Hearing their compliments about how our school
and university have well prepared their kids and loved ones to become the finest biomedical engineers or simplify seeing the smiles on their face has made all our hard work worthwhile and made all of us so proud of what we have accomplished.
It
was good to see Leo, Jackie, Tami, and Elsje at the commencement for hooding their respective students and seeing them through the journey all the way to the end. Leo also served as a Marshall beautifully. It was a good surprise to see Doug Brubaker there.
You exemplify what we stand for in this fine institution with excellent work on one of the most important missions, if not the most important one. That is, training next generations of world-class engineering researchers and independent thinkers who can go
on to save lives, improve health outcomes, and make the world a better place. Congratulations to all the graduating students who are leaving Purdue soon. I am confident that you will represent Purdue and Purdue BME so well along your exciting and successful
academic and professional career.
All
the above events were successful. Many thanks to the many organizers, Darshini, Rhonda, Pam, Susan, Tammy, and the BME student ambassadors, who put in so much energy.
In
the Staff Appreciation meeting on last Monday (5/6), we had a surprise. Asem
Aboelzahab received the Sandra K. Monroe Award. The Sandra K. Monroe (the person by Asem in the picture on the left) Excellence in Student Services Award is given annually to one student-facing professional for their policy advocacy and/or exemplary service
to students. This is a university-wide award. Attached please find a few pictures taken at the presentation. So good to see some of the graduate students who wrote the support letters came to the presentation to celebrate Asem’s achievement. So good to hear
some of the faculty’s heartfelt remarks on Asem and his great student services.

The
staff appreciation meeting was a success. It was so well organized by a few faculty members that many staff were caught by surprise. We wanted to celebrate them and thank them for all their support.
Norvin
Bruns, was selected by CSSAC Staff Excellence Award Selection Committee, as the recipient of the CSSAC Annual Service Award.
Norvin embodies excellence in every aspect of his work within the Weldon School of Biomedical Engineering at Purdue University. His dedication, initiative, exemplary
service, leadership by example, and high performance made him an exceptional candidate for this recognition. He and Asem probably are the two most known persons in the department among our students. Congratulations to Norvin.
I
will continue to do one round of acknowledgements for those who have received awards in the past academic year. The following students have received a Grubbs Undergraduate Research Scholarship:
Noah
Jasinkiewicz, Aavya Srivastava, Molly Dye, Shiv Shukla, Samantha Campbell, Aaron Coppeta, Sarah Grev, Jean-Paul Pertuit, Dalton Aaker, and Tyler Merrill. This scholarship is used to recognize students who have successfully fulfilled the requirements of BME

Title of research: Evaluation of Biodegradable in situ Forming Implant Components to Advance Extended Release ISFI Treatment for Opioid Use Disorder.
Thesis
Committee: Luis Solorio (Chair), Kinam Park, Andrew Otte
Abstract:
Opioid use disorder (OUD) presents a challenging and nuanced condition with potential for debilitating social and physical consequences. Patients with OUD have access to treatment options, but they may
encounter issues such as diversion, invasiveness, or poor adherence. With over 2.5 million adults in the US experiencing OUD as of 2021, the need for an OUD treatment that overcomes these challenges is clear. One available treatment method is Sublocade®, a
PLGA-based in situ forming implant (ISFI) that releases buprenorphine. This treatment shows promise due to its physician administered extended release design, which addresses many current issues in OUD treatment. However, the practicality of this treatment
remains a challenge due to its monthly injection requirement. To address this, we investigated how altering ISFI components impacts the timeframe of buprenorphine release from a PLGA-based ISFI. Our focus was on evaluating factors that lead to extended buprenorphine
release while maintaining zero-order release. We varied polymer-to-solvent ratios, drug content, and solvent type, assessing their effects through drug release studies. We also conducted SEM imaging and swelling/erosion studies to evaluate polymer behavior
and implant microstructure, gaining further insights into drug release mechanisms. Our drug release studies revealed that higher buprenorphine content in the implant significantly reduced total drug release and linearized drug release patterns. Decreasing
the polymer-to-solvent ratio similarly linearized drug release and reduced drug burst, although the overall amount of drug released over time remained similar. Introducing Triacetin (TA) as a solvent helped reduce drug burst and maintain release linearity
in lower drug content implants. In higher drug content implants, TA appeared to increase drug release over time, likely due to degradation processes indicated by high swelling and increased degradation observed in SEM imaging. Erosion studies showed less implant
erosion with higher drug loading, aligning with release study observations. In conclusion, solvent type and drug content significantly influence buprenorphine release in ISFI systems and should be carefully considered when designing extended release systems
similar to Sublocade®.

Influences on Bone Mechanosensitivity: Mechanical Load Distribution History and Alterations in the Gut-Bone Axis
Thesis
Committee members: Dr. Dianne Little (co-chair, BMS), Dr. Deva Chan (co-chair, BME), Dr. Timothy Lescun (VCS), Dr. Andrew Brightman (BME), Dr. Glen Niebur (University of Notre Dame)
Abstract:
Osteoporosis is a bone disease that affects over 20% of the global elderly population. It is characterized by reduced bone mass and strength, leading to increased fracture susceptibility due to diminished responsiveness to mechanical stimuli. Understanding
how bones sense and respond these mechanical signals is crucial, as it directly relates to osteoporosis severity and fracture risk. There remains a critical need to identify the key factors influencing bone mechanosensation to develop effective interventions
for osteoporosis patients. Tissue-level mechanical strain directs bone adaptation. Non-physiological strain distributions can induce bone formation even under normal strain levels, highlighting the significant impact of strain distribution on bone mechanosensitivity.
Physiological strain is influenced by daily locomotion patterns, which vary across species. For instance, sprawling locomotion in reptiles with distinct stances and load distributions from quadrupedal mammals, may establish novel bone mechanosensitivity pathways.
Additionally, systemic perturbations like disrupted gut microbiome (GM) diversity – dysbiosis, alter bone homeostasis through inflammatory changes, affecting bone quality. Antibiotic use disrupts long-term GM diversity and may influence bone adaptation and
mechanosensation, while exercise may offer restoration. However, specific responses of osteocytes to different strain modes, the impact of locomotion stance on bone mechanosensitivity, and the interplay between GM dysbiosis and exercise on bone health remain
unclear. We hypothesize that these mechanical load experience and systemic interference impact bone metabolism. Aim 1 will assess the effects at the level of gene expression of different strain distribution patterns during loading using two external mouse
tibia loading models on bone cells. Aim 2 will investigate bone remodeling responses in sprawling hindlimb gait quadrupeds using iguana models. Aim 3 will study the interplay between antibiotic-induced GM dysbiosis and treadmill exercise on long-term bone
homeostasis using mouse forelimb bones. Understanding the factors influencing changes in bone mechanosensation is essential for developing new drug targets and mechanical stimulation for osteoporosis patients. Completion of this project will help me develop
the skills necessary for my long-term goal of becoming an independent researcher in musculoskeletal biology, osteoporotic disease, and sport sciences.

PhD Preliminary Examination Announcement for Jae Young Park (Hyowon
Lee, advisor). Everyone is invited to attend the public presentation beginning at 10:00 AM in MJIS 2001.
Research title: Towards advanced implantable microsystem for minimally-invasive and precise neuromodulation.
Thesis Committee members: Dr. Hyowon Hugh Lee (chair, BME), Dr. Chi Hwan Lee (BME), Dr. Young L. Kim (BME), Dr. Albert Lee (BME)
Abstract: Neuromodulation
is increasingly utilized to rehabilitate a variety of biological functions, such as vision, hearing, movement, touch perception, and sense of self-movement, particularly in patients with severe or chronic diseases for whom other treatment options, including
medication, have proven ineffective. Nevertheless, due to concerns about the cost and safety of surgical processes, many are hesitant to proceed with this option. Concerns particularly arise from the potential displacement of the electrode caused by movements
at the target site due to air infiltration or cerebrospinal fluid loss during surgery. Other issues including technical errors, failure in lead fixation, Twiddler syndrome, and Pneumocephalus can also result in electrode dislocation. This misalignment can
lead to off-target effects that can have severe repercussions for patients. In address these issues, we have developed two novel platforms and accompanying surgical strategies to enable safer, more accurate, and easier implantation. To achieve these multifaceted
objectives, we designed a stretchable thin-film electronic device using polyimide-based microfabrication techniques, which is compliant to other functional medical platforms. By integrating this device with silicone catheter and adhesive hydrogel, we have
endowed the device with new functionality that facilitates novel implantation methodologies. Additionally, the third research objective of combining fractal design and surface roughening methodology led to the successful development of a highly stable stimulating
electrode.
