Mechanical engineer designing drug delivery devices.
I design the mechanisms inside injectors — wearable insulin pumps, pen injectors, autoinjectors and passive needle safety devices — from first concept through 3D printed working prototypes, human factors studies and regulatory documentation.
Selected work
10 projectsThe drug delivery devices were developed at Mediscient Devices. Their internal mechanisms are confidential, and several have patents pending — those pages show what the devices do and what I contributed, not how the mechanism works.
Wearable Bolus Injector
A smart, low-cost wearable insulin injector for developing markets, with a purely mechanical delivery mechanism and a Bluetooth data logger.
0.5 mL Needle Safety Device
A passive needle safety device for high-viscosity depot drugs, designed around Lanreotide and the enlarged hands of acromegaly patients.
Fixed Dose Pen
A pen injector for low-viscosity drugs like Teriparatide, with the fewest parts of any comparable device and a dose counter built into the plunger rod.
Variable Dose Pen
A reusable dial-a-dose pen injector for drugs like insulin, where the dose changes day to day.
Autoinjector
A single-use autoinjector with an integrated needle safety sleeve, taking the clinic visit out of subcutaneous, intramuscular and intradermal injections.
1 mL PFS Needle Safety Device
A three-part retrofit that adds passive needle safety to glass pre-filled syringes without touching an existing filling line.
Intradermal Injectors
Prototype work on intradermal delivery using a short, shallow needle array.
Microneedle Platform for Wearable Drug Delivery
Hollow 3D printed microneedle patches meant to replace the indwelling needles used by commercial wearable injectors.
All-Terrain Vehicle Research Group
Head of design for a university team building a genuinely tough all-terrain vehicle: 12 kg lighter, generatively designed wheel assemblies, and a driver cage validated by explicit dynamics.
Covid-19 Analytics
A modified SEIR model of the Covid-19 outbreak in India, run across six lockdown strategies to find the one that minimises deaths without shutting the economy indefinitely.
About
I’m a mechanical engineer who designs drug delivery devices — wearable insulin injectors, pen injectors, autoinjectors and passive needle safety devices. Most of my work is the mechanism: the small stack of moulded parts and springs that has to deliver an exact dose, retract a needle and lock itself, reliably, at a price a developing market can absorb.
Enthusiastic about design, medical devices, cars, martial arts and chess.
