20 Types of Scientists | A Guide on Their Study and Contribution to Society

Scientists help in human development and progress in technology in the current lifestyle.

There are different types of scientists who work in various areas of science to gain more knowledge.

They contribute to better health, quality products, safety measures, ease of living, and enhancement in the economy and employment.

The options like industrialization, the internet, social media, and connectivity that humans enjoy now are products of the collective efforts of scientists working in different sectors.

20 Different types of scientists and what they study

  • He is mainly concerned with how the drug, once administered, behaves in the body.
  • How it produces the therapeutic effects, the metabolism, toxicity, and side-effects of the drugs.

8. Nutritional Scientist/dietitian

  • The one who assesses the nutrition contribution of different foods and their contribution to the well-being and treatment of malnutrition.
  • They can work in sports nutrition and medical nutrition therapy as clinical dietitians, community dietitians, etc.

9. Social scientists

  • This is a group of similar scientists who can be defined based on their area of social research like

10) Anthropologist

  • Is one who studies aspects of human society of the past and present.

10) Archaeologists

  • These are a group of scientists who try to explain past human activity by exploring past remains.

11) Geographers

  • As the name indicates, they study the region’s land, habitat, and human life.
  • They also help in making maps.

12) Historians

  • These scientists try to explain history from the available records or events.

13. Physicist

  • He is a scientist with knowledge and curiosity in the field of physics.
  • The knowledge involves interactions of matter and energy at all time scales in the universe.
  • Based on observation, these scientists postulate laws or principles that help understand the universe principles like gravitation, motion, time, etc.
  • Examples of great scientists in this area include Isaac Newton and Albert Einstein.

14. Nuclear physicists

  • These scientists study the structure, characters of atomic nuclei, and interactions of its components.
  • The work of these scientists helps in the development of nuclear energy, X-rays technique, and other radiation-related methods.

15. Chemical scientist

  • The science of chemistry is so vast. The work involves discovering the chemical structure of any compound either from nature or obtained by synthesis.
  • Also, they formulate methods to identify a substance and determine its chemical and physical properties.
  • Further, they also identify their uses and toxic properties. 
  • Many scientists are involved in the research of chemistry in different areas of study like

a) Organic chemists

  • They are concerned that the study of pure organic compounds is so wide, and most compounds, including drugs, poisons, and disinfectants, are organic in nature.
  • They try to study the structure, synthesis method, and reactions of these compounds.

b) Biochemist

  • These scientists study the organism’s source of food, digestion, metabolism, and excretion.
  • They also study processes like fermentation, transcription, translation, etc.
  • They are the ones involved in the human genome project.

c) Medicinal chemists

  • The scientists in this area study the structure of available drug molecules and explore the structure by a further modification to find more new molecules.
  • They also try to minimize the toxicity of existing medicine by suitable modifications in the parent molecule.

See chemistry in medicine for more.

d) Inorganic chemist

  • These chemical compounds are used in daily life like table salt, baking soda, talc, etc.
  • There are many inorganic compounds, and they are explored for their chemical and physical properties.

Further, their uses and harmful effects are sorted out.

e) Analytical chemist.

  • Analytical chemistry tries to analyze the substances.
  • Scientists involved try to find new ways to determine a substance with more accuracy, in a shorter time in an inexpensive way.

16. Astronomers

  • They are the scientists who study celestial objects like planets and stars and the details of how they are formed, behave, etc.
  • They help discover new stars and comets by the use of telescopes.

17. Biologists

  • These scientists study living beings and their characters in all forms.

They are again of different types like

a. Zoologists

  • These are scientists who study animals in detail.
  • They focus on animals’ origin structure, living habitats, genetics, reproduction, etc.
  • They also try to predict and explain the evolution of animals.

b. Botanist

  • Is one who explores the knowledge about plants.
  • They try to understand the evolution of plants, their physiology, growth, age, etc.
  • Further, they explore the distribution of plant species and types in the nation and the world.
  • They also define methods to identify the plants and study the external and internal structure of plants.
  • Even the uses of plant constituents are explored. Hence, we use plants for medicine, dye, textile, and other uses due to plant studies.

c. Microbiologist

  • This person studies microorganisms like bacteria, viruses, protozoa, fungi, algae, etc.
  • He is also concerned with methods like sterilization (destruction of microbes), disinfection, body immunity, vaccination, etc.

d) Bacteriologist

  • They are specialized in the knowledge of bacteria. This includes their classification, distribution, food habits, benefits to man, etc.

e) Virologist

  • A scientist with immense knowledge of the viruses, their emergence, growth, distribution, pathogenicity, etc.

d. Bio-technologist

  • He studies the genetic and other traits of living beings and develops new biological entities to benefit humanity.

e) Ornithologists

  • These scientists are involved in the study of birds.
  • Their main focus is the study of the behaviors, habits, habitats, migration, and other features of birds.

f) Entomologist

  • He tries to classify insects and study their anatomy, physiology, food habits, reproduction, and life cycle.

g) Ichthyologist

  • He is the one who is involved in the study of fish. This includes their anatomy, characters, habits, habitats, etc.

i) Marine biologist

He is the one involved in the study of animals in the sea and ocean.

They study a variety of aquatic organisms starting from the minute plankton and major animals.

18. Agriculturist

  • Scientists are concerned with the methods and improvement of agriculture. They study crop varieties, soil characters, crop disease, etc.
  • Their goal is to enhance crop yield, prevent diseases, and survive drought and other conditions crops.

19. Environmental scientist

  • These scientists advise about global warming, melting glaciers in Antarctica, and the possibility of sea-level rise risking coastal cities.
  • They study the reasons for pollution, global warming, and methods to prevent or overcome these problems.

  1. “Environmental scientist” isn’t a real thing. Never has been. Scientists can, and do, advise on environmental issues, but that doesn’t make them “environmental scientists”.
