First Forum Presentation

 Exciting News from our Lab! 

We're proud to share that two of our talented third-year PhD candidates in Neuroscience, William Quackenbush and

Hari Srinivasan, recently presented their research at the Vanderbilt Brain Institute's Neuroscience Graduate Program Research Forum! 


This was their first time presenting at the forum, and both talks were incredibly well received.


 Coinciding with Autism Month of April, Hari Srinivasan presented his research on: "Virtual Bubbles, Real Insights: Investigating Peripersonal Space (PPS) in Autism." Hari's work explores how autistics process the space around their bodies, offering a novel perspective on sensory-motor integration.


 In March, William Quackenbush presented his research on: "Regulating Rhythms: Elucidating Brain-Behavior Relationships of Motor Stereotypies Across Sensory Landscapes." His work focuses on motor stereotypies (or stimming) in autism, aiming to understand the sensory and motor dynamics that shape these behaviors.


 Both William and Hari are co-mentored by Prof. Mark Wallace at Vanderbilt and Prof. Carissa Cascio (now at the University of Kansas, Lawrence). They are also NISE Fellows (Neurodiversity Inspired Science & Engineering Fellows) at the Frist Center for Autism and Innovation, reflecting their commitment to advancing autism research through innovative and interdisciplinary approaches.


 It’s exciting to see these promising areas of research being presented at the forum! Congratulations to both William and Hari on their well-received presentations!










Caught Between Tears and Stoicism

It’s a catch-22: If we don’t show emotion, we risk being labeled as "cold" or "unexpressive"; if we do, we might be seen as "overly emotional."

 My Ted X talk titled "Pebbles in the Pond of Change

Hari Srinivasan, shares a powerful message about the power of small actions in creating ever-widening ripples in the pond of change. Drawing from personal experiences and the legacy of disability rights leaders, he redefines progress as a journey that starts with simple, accessible steps. His inspiring message encourages everyone to identify and act on their own "small pebbles" to drive societal transformation.

How Reasonable are Reasonable Accommodations at Work

 

As we observe National Disability Employment Awareness Month in October, it is essential to create true equity for all autistic and neurodivergent workers by closing this loophole around the subjectivity of “reasonable accommodations

Disability and Multilingualism

Just as ramps and elevators, which were initially designed for wheelchair users, can aid travelers with suitcases and families with strollers, solutions that support those with significant support needs in the autism community can enhance accessibility and inclusion for all.

Oversampling

Just as psychology research had its WEIRD (“western, educated, industrialized, rich and democratic”) sampling bias, autism research has not only a WEIRD sampling bias, but also has essentially oversampled the same, narrow band of what are considered the easily “researchable autistics,” and expected those findings (as well as the applications and interventions that resulted from them) to apply to everyone.

Participant Selection Bias


"Research participant selection bias is especially problematic in... autism because research [not only] provides explanations [but] also influences policy priorities, interventions, treatments, who gets access to funding, access to spaces, and even societal attitudes. Most importantly, research leads us to applications and solutions."
-Hari Srinivasan, Time

Temporal ventriloquism


Temporal ventriloquism refers to the brain's ability to synchronize slightly misaligned visual and auditory inputs, which may work differently in autism, leading to challenges in processing multisensory information. 

PlainSpeak. In Plain Language for the Lay Reader

Temporal ventriloquism is when the brain adjusts sounds and visuals that don’t match up perfectly, making them seem like they happen together. In autism, this process might work differently, which can make it harder to handle mixed sensory information.

Challenges-Based-Solutions

"For some autistics, we can step right into the application of positive psychology. For others, we need to be working on challenge-based solutions at the same time. It’s not a binary, either/or situation where you do one at the expense of the other." - Hari Srinivasan

My research interests

Read here to learn more about me. My graduate research investigates peripersonal space (PPS) in autism, exploring how differences in sensory-motor integration impact spatial perception and interaction. PPS is the immediate space around our body—like a flexible, invisible bubble—where we perceive actions as directly affecting us. It serves as a critical sensorimotor interface, shaping how autistics navigate our social and spatial environments. Understanding PPS dynamics in autism has broad implications across education, employment, and daily living skills.

I employ behavioral, physiological, and neurological measures using immersive technology like VR, AR, and motion tracking to study these processes in a dynamic, real-world-like environment. My approach prioritizes ecological validity, simplicity, and participant comfort, so that a wide profile of autistics can participate in research — capturing a more comprehensive understanding of sensory-motor differences that span the spectrum of autism.


Ultimately, my work aims to bridge the gap between basic neuroscience and applied interventions, informing strategies that can help autistics navigate their sensory environments more effectively. I will also be looking to developing tailored intervention(s) based on PPS insights. As both a researcher and an autistic with ADHD, I am deeply committed to research that not only advances scientific understanding but also has practical real world applications and solutions.
