I work with individuals, businesses, researchers, and organizations for consulting, mentoring, scientific expertise, research support, and professional problem-solving.
I took a PhD at Zhejiang University (ranked among top 50 globally) on spin-labelled novel polymers. Since then I have taught polymer chemistry, supervised graduate research, spent a postdoctoral year, and now work in industrial R&D. The through-line is the same: materials that have to perform, and people who have to be able to explain why.

What clients say
Kaleem was highly professional, he understood the job well, promptly asked for any clarification, notified of issues and completed tasks quickly. I was extremely satisfied with his attention to detail - he double checked everything several times. His pricing was reasonable and he did not ask for more, even though there were a few additional tasks. He was very patient in his manner and overall just a pleasure to work with. I will not hesitate to hire him again or to recommend him to colleagues.

Projects
Past Projects & Collaborations
01
National Resilience Index: Methodology & Stability Testing
Retained as academic consultant on a national resilience index programme, responsible for the methodological rigour behind it. Stress-tested the indicator set and underlying data definitions, ran stability and sensitivity testing across the scoring weights to confirm the index did not swing on noise, and reviewed the narrative that would have to survive a ministry briefing — so it would read as a measurement instrument, not a brochure.
PPwCUnited Kingdom
02
Complete Book: Biochemical Processes in Metabolic Disorders
Commissioned to write a full-length book on the biochemical processes behind common metabolic disorders, and how the pressures of modern life — diet, stress, environmental exposure — drive them. Structured the science from mechanism to lived condition, with evidence a general reader could follow without flattening it, and carried a full manuscript to completion.
CChuck G.United States
03
Enzymatic Route Feasibility for Plant-Scale Process Conversion
Directed a technical review of enzymatic routes proposed for a plant-operations upgrade, assessing reaction kinetics, published yield data, and process-window claims against what the literature actually supports. Mapped the gap between bench-scale enzyme performance and plant-scale conditions — temperature stability, substrate concentration, downstream separation — and defined the trial data a factory team would need before committing capital to a pilot run.

PA66 Glass-Fibre Component Warpage in Automotive Cooling Systems
Investigated dimensional warpage and cracking in 30% glass-fibre-reinforced PA66 components for a coolant-management assembly, injection moulded near 285°C melt / 80°C mould temperature. Reviewed DSC, TGA, moisture-content data, moulding parameters, fibre orientation, and part-to-part dimensional records. Identified non-uniform mould cooling and excess resin moisture as the major contributors, and recommended resin conditioning, revised drying controls, and cooling-cycle optimisation ahead of any tooling change.
CConfidential Automotive OEM
05
TPU Degradation in Automotive Fuel-System Components
Investigated loss of flexibility and surface cracking in thermoplastic polyurethane components exposed to automotive fuel and elevated temperature. Samples were accelerated-aged near 80°C and benchmarked against unaged controls, using FTIR spectroscopy, tensile testing, hardness measurements, DSC, and mass-change analysis to separate chemical degradation from mechanical fatigue and identify the dominant failure mode.
CConfidential Automotive Supplier
06
Sustainable Polymer Formulation Assessment
Evaluated several lower-impact raw-material options for replacing components in an existing polymer formulation. Compared technical performance, processing requirements, compatibility, expected durability, and practical manufacturing constraints rather than relying solely on sustainability claims.
EE Sustainable Materials CompanySweden
07
Process Troubleshooting for High-Viscosity Formulation
Investigated unexpected increases in viscosity during production of a specialty chemical formulation. Examined mixing sequence, temperature profile, solids concentration, raw-material variation, and shear conditions, and developed a troubleshooting matrix for plant operators.
KK Specialty Chemicals ManufacturerMalaysia
08
Technical Review for New Product Development
Provided an independent technical assessment of a proposed polymer-based product before further investment. Reviewed the formulation concept, available experimental data, manufacturing route, performance claims, and key technical risks, and prepared a prioritised development roadmap.
VV Materials StartupSingapore

Manuscript & Reference-List Polishing for Journal Submission
Polished five consecutive research articles and their reference lists for submission, checking citation formatting and consistency and bringing each manuscript up to the target journals' requirements before submission.

Industrial AI model for plant operations
Prepared a production-facing model for a process company: feature design against plant data, validation that a process engineer could defend, and documentation so the model could be owned internally rather than remaining a black box on a laptop.
HHelios Process SystemsGermany

Analytical review of a research paper
Independent analytical review of a chemistry manuscript: methods, data treatment, and whether the claims were earned. Written so the author could act on it — not a referee’s shrug, a working diagnosis.

Industrial due-diligence chemistry pack
Built the technical spine of a buy-side pack on a process asset: what the plant chemistry implies for yield, waste, and capex, in language a deal team could take into a data room without a second translator.

Bioprocess scale-up dossier
Turned scattered lab notes into a scale-up dossier a manufacturing board could read: critical process parameters, failure modes, and the experiments still missing before a pilot line is committed.

Heavy-duty industrial coating reformulation
Led the chemistry on a reformulation for aggressive industrial service — corrosion, UV, and chemical splash — including raw-material substitution and a QC spec the plant could actually run.

FAQs
Questions people ask before they write
What kind of work do you take on?
Consulting, mentoring, scientific expertise, research support, and professional problem-solving — for individuals, businesses, researchers, and organizations. Chemistry and materials science are where I go deepest, but if you are not sure it fits, describe the problem and I will tell you honestly.
Will you sign an NDA?
Yes — just ask, on the side panel or when we first speak, and I will send one over before we get into any detail.
How quickly do you reply?
I read every enquiry myself, usually within an hour. If it is urgent, say so in the subject line or message me directly on WhatsApp.
Do you work with companies, or only individual researchers?
Both. I have worked with organisations such as PwC, Deloitte and Nestlé alongside individual researchers, and I hold top-rated consultant status on Upwork, Freelancer, and Fiverr.
What does a project cost?
It depends on scope. Share a brief and a rough budget through the form above and I will tell you honestly whether it is a fit before anything is agreed.
Can we work together on an ongoing basis, not just one project?
Yes — I'm flexible, and we can discuss whatever kind of collaboration suits the work, whether that's a single project or an ongoing retainer. Tell me what you have in mind and we'll figure out the shape that fits.
Do you provide mentoring to students?
No. I do not take on students' coursework, theses, dissertations, or writing/editing support of that kind — my mentoring and consulting work is for businesses, researchers, and organizations.
