Research / Leadership / Public engagement

Science beyond the laboratory.

At the fifth Chemistry Festival, I stood before an audience to present the chemistry our student chapter wanted people to encounter for themselves. At Qatar University we also built workshops and instrument-training opportunities for other students; later, I was invited to judge school research. I have worked on experimental imaging practice as well. Each activity demanded care with the evidence, whether the audience was a laboratory colleague, a student or someone seeing a chemistry demonstration for the first time. The records below identify my role and the work undertaken with others.

2015–2019 · Chapter leadership

Helping build a chemistry community at Qatar University.

As a founder and leader of the American Chemical Society student chapter at Qatar University, I helped develop a student-led setting for workshops, chemistry demonstrations, scientific discussion and engagement with the wider community. The chapter's work emphasized opportunities for young chemists to acquire technical skills and communicate chemistry outside the classroom. Among the documented activities were Chem Talks, hands-on instrumental-methods training for 29 students, and chemistry demonstrations.

One contemporaneous record is the August 2018 poster at the 256th ACS National Meeting & Exposition, titled “ACS Qatar University's Chapter: Updates on the Approach of Qatar University's Chapter to Empower Young Chemists and Reach Out to the Community.” Its scope documents chapter development, academic growth, community outreach, public service and professional development. The poster is a historical record of the collective chapter, not evidence that every event was personally delivered by one individual.

Evidence: The LinkedIn attachment carries the label “Chapter Presentation – 2019,” while the scholarly record dates the poster to August 2018. See the poster record (DOI: 10.13140/RG.2.2.32073.67684) and the original LinkedIn media; the upload label should not be treated as the date of first presentation.

Public chemistry · 2015–2020

When chemistry became a conversation with strangers.

Some of my most memorable work in chemistry happened outside the laboratory. At The Chemist Café, our student chapter helped turn demonstrations and public meetings into encounters with people who might never have visited a chemistry department. I also took on a public-facing role as an MC at a Chemistry Festival. Speaking to an audience meant learning to respect its curiosity, explain what a demonstration could establish, and resist the temptation to make science sound more certain than it was.

These were collective activities undertaken through the American Chemical Society student chapter at Qatar University. The chapter's 2017 conference poster includes Figure 2, “The Chemist Cafe”, while its 2018 poster documents Figure 20, public meetings at The Chemist Café. Those contemporary records establish the programme; the date and event associated with any particular archive photograph still need to be checked against its original source.

Experimental records · Microscopy

The recordings show cardiovascular movement and optical microscopy in zebrafish, alongside separate footage of avian egg preparations. Motion reveals changes that a still micrograph cannot capture. The related methods and publications are linked nearby.

Laboratory archive · 2017

The ordinary photographs of experimental work.

Research histories often show only completed figures. My earlier photographs include something less polished but equally real: materials laid out before an experiment and the instruments needed to make the work possible. The labels in the photo library locate these images at Qatar University in April and July 2017. They do not establish the full experimental protocol or identify a particular published result.

6–7 May 2023 · Conference organization

Qatar University · Biomedical Research Center

Helping bring an international biomaterials conference to Qatar.

In May 2023 I served on the organizing team for the First International Biomaterials Conference in Qatar, hosted by Qatar University's Biomedical Research Center. The meeting brought researchers, clinicians and students into the same room to discuss biomaterials, biosensors and microfluidic technologies for medical applications. Its subjects included tissue engineering, nanomedicine, targeted drug delivery and lab-on-a-chip research.

My original conference identification, marked ORGANIZER, survives in my personal photographic archive. It is a small record of work that often stays outside a scientific CV: helping make a meeting possible so that researchers can exchange ideas in person. The event was organized institutionally by the BRC with support from Qatar University and Qatar National Research Fund; my role was as a member of the organizing team, not the conference chair.

Scientific evaluation · Qatar

Evaluating student research at Al Thakhira Youth Center.

I was invited by Qatar's Ministry of Education and Higher Education and Al Thakhira Youth Center to serve as a judge for research projects presented by students from schools in northern Qatar. The invitation extended my scientific engagement into student research evaluation, where experimental logic, evidence and clear communication matter as much as the final presentation.

Public health · Ministry of Sports and Youth, Qatar

A research competition on youth health.

I participated in the research competition “Sports as a Way of Life: Towards Youth Awareness of Obesity Risks and the Importance of Promoting Healthy Lifestyles.” Qatar's Ministry of Sports and Youth issued a certificate of appreciation recognizing my active participation.

ACS Student Chapter · Qatar University

Hosting the fifth Chemistry Festival.

I hosted the 5th American Chemical Society Student Chapter Chemistry Festival at Qatar University, helping turn the chapter’s commitment to public service into a participatory science event. The programme brought chemistry demonstrations and interactive learning to visitors, illustrating how chemical phenomena connect to everyday life. The event was a collective undertaking by chapter members and their supervisor; my documented role was as host and presenter.

The event photographs shared from my Instagram post show me speaking into a microphone in front of the ACS display and an interactive quiz, and visitors gathering around a live demonstration. These are records of science communication and student-led outreach, not evidence of an independently organized event.

Primary evidence: Instagram post by @mahmoudkh23_, caption beginning “I had an incredible time hosting the 5th American Chemical Society Student Chapter Chemistry Festival at Qatar University!” The two event images and accompanying caption were supplied directly from the post. The event year is not stated in the provided screenshots.

Experimental biology · Microscopy

Watching development at the scale of the whole organism.

My zebrafish work involved handling and observing embryos and larvae, microscopy, developmental assessment and imaging workflows relevant to vascular biology and experimental physiology. The images supplied with this record depict distinct developmental appearances, including chorion-enclosed embryos and a hatched larva. They are examples of biological material observed under the microscope, not a quantified phenotypic result.

Reliable scientific interpretation requires the original metadata: magnification, embryo age in hours post-fertilization, genotype, imaging modality, specimen identity and experimental condition. These details cannot be inferred from photographs alone, and are deliberately not invented here.

Research context: The imaging and physiology case study and research techniques atlas explain the microscopy and quantitative-workflow background.
